[Bug fortran/48352] [4.7 Regression] segfault in fortran/frontend-passes.c
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48352 --- Comment #8 from Joost VandeVondele Joost.VandeVondele at pci dot uzh.ch 2011-04-01 06:17:51 UTC --- BTW, from this experience, it would be great to have the frontend optimizations being protected by a switch (-f(no-)frontend-optimizations or similar) which can default to true at -O1 and higher. First, this would provide an easy workaround for this kind of bugs. Second, this would make sense in combination with LTO, where in principle one could compile in the first pass with -O0, and only at link time with -Ox (this makes sense from a compile time point of view). However, for this to generate good code, the first pass should be -O0 -ffrontend-optimizations, otherwise the middle end would have no chance.

[Bug other/48378] gcc 4.6.0 fails to build from source
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48378 --- Comment #5 from Jonathan Wakely redi at gcc dot gnu.org 2011-04-01 08:36:20 UTC --- Building in a separate dir has the advantage you don't need to make clean, you just remove the whole dir and start with an empty dir again. I'm not sure 'make distclean' helps, does it make any difference if you start again extracting the source tarbal into an empty dir and build in an empty dir? If not please provide your exact configure command (just ../gcc-4.6.0/configure?) and the error.

[Bug middle-end/48377] [4.6 regression] miscompilation at -O3
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48377 --- Comment #4 from Jakub Jelinek jakub at gcc dot gnu.org 2011-04-01 09:51:06 UTC --- Anyway, please read http://gcc.gnu.org/bugs.html, there is nothing we can do from the information you've provided. Trying to find from a vague description of where you see the crash a difference in assembly is very hard, plus it may very well be just a bug in the sources you are compiling. If -O2 works and -O3 doesn't, try to add __attribute__((noinline)) resp. __attribute__((optimize(2))) resp. __attribute__((optimize(3))) to various suspect routines in the file to try to narrow it down to a single problematic routine (perhaps with some functions inlined into it), which will work fine if the whole file is compiled with -O3 just that routine is -O2 (and perhaps functions inlined into it) and will misbehave if everything is compled with -O2 just that function is compiled with -O3. Then try to make a self-contained executable testcase out of it (just call that routine from some other CU's main, perhaps with the minimal necessary setup for it and stub everything it calls. For (suspected) miscompilation we really need to be able to reproduce it ourselves, preferrably with a minimal testcase, otherwise we can't do anything on it unless you debug the problem yourself down to pointing a bug somewhere exact in the assembly.

10:15:24 UTC ---
yes, the patch looks correct to me and should go on the 4.6 branch as it's a
regression caused by http://gcc.gnu.org/viewcvs?view=revisionrevision=158682
when we started using deleter_type::pointer
Prior to that change this slight variation worked ok:
#include memory
#include cassert
struct my_deleter
{
typedef int* pointer;
void operator()( void* p ) {
delete static_castpointer(p);
}
};
int main()
{
std::unique_ptrvoid, my_deleter p( new int() );
assert( p.get() != 0 ); // invalid conversion from 'void*' to 'int*'
p.reset(); // no matching function for call to 'swap( void*, int* )'
}
I won't be at home to test and commit it until tomorrow though

I am trying to compile the following simple code snippet:

#include stdio.h

va_list function(int i, va_list args){

}
int main(void){

I am running 64 bit Ubuntu. The code can be compiled successfully using.
gcc -Wall test.c -o test -m32
However if I compile using the standard 64 bit mode

I get the following error:

test.c: In function 'function':
test.c:5: warning: return makes integer from pointer without a cast
The above code does not serve much purpose other than to demonstrate where the
compiler seems to be breaking.

The library obtains the available kinds at library compile time by asking the compiler for the available kinds. Thus, seemingly the compiler which compiled libgfortran supported REAL(16) while the compiler currently installed on your system does not. Thus: How have you obtained the compiler? Are you sure that the correct compiler/library combination is used? It seems as if you mix libgfortran of GCC 4.6 with a gfortran of GCC 4.x 4.6. In principle, the libgfortran library is downward compatible, however, the current versioning system does not quite anticipate that different GCC versions might support different REAL kinds - I also do not see how one could easily fix this - using, e.g., --disable-libquadmath-support, you could now build a 4.7 which does not support REAL(16) but which is otherwise fully compatible with a 4.6 which supports REAL(16) - unless one then uses REAL(16) functions.

The run time executable is finding a more recent copy of libgfortran. For example if you have set LD_LIBRARY_PATH to point to a local build of experimental, your normally installed gfortran compiled programs will find the experimental library first. Another possibility, as Tobias hints at, is the distribution people have mixed versions of libgfortran on you. Regardless it is out of sync. Let me know if you find it.

[Bug libstdc++/48406] New: algorithm #undefs isfinite() from math.h in C++0x mode
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48406
Summary: algorithm #undefs isfinite() from math.h in C++0x
mode
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: jyass...@gcc.gnu.org
$ cat test.cc
#include math.h
#include algorithm
bool foo(double d) {
return isfinite(d);
}
$ ~/opensource/gcc/git/install/bin/g++ -c test.cc
$ ~/opensource/gcc/git/install/bin/g++ -c test.cc -std=gnu++0x
test.cc: In function ‘bool foo(double)’:
test.cc:5:20: error: ‘isfinite’ was not declared in this scope
test.cc:5:20: note: suggested alternative:
.../include/c++/4.7.0/cmath:528:21: note: ‘std::isfinite’
$
This is a regression since gcc-4.4:
$ g++-4.4 -c test.cc -std=gnu++0x
$
It happens because stl_algo.h includes random in C++0x mode only, and
random includes cmath, which #undefs all the C99 math functions that
math.h defined, without 'using' the std functions back into the global
namespace.
As far as I can tell, [depr.c.headers] says that math.h puts the cmath
names into the global namespace, and it doesn't allow a later include of
cmath to take them back out. [depr.c.headers] also allows cmath to
unconditionally put its declarations and definitions into the global namespace,
which is what I'd propose as a fix.
