[Bug bootstrap/21288] bootstrap issues with profiledbootstrap
--- Additional Comments From bh at techhouse dot brown dot edu 2005-05-02 17:58 --- I get the same error with 'make bootstrap' -- it's not the profiling that causes the ICE. Similarly, I get the same error when I download the full tar file, so it's also not a packaging bug. If there's any other information that would help, I'll happily provide it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21288
[Bug bootstrap/21288] New: fortran bootstrap issues
(1) if you download core, g++, and fortran, only c and c++ are built; fortran is
not, unlike in prior releases.
(2) configuring with --enable-languages=c,c++,f95 and no other options; then
using make profiledbootstrap, I get an ICE:

[Bug c/19058] New: setjmp: 4.0 fails to give 'clobbered' warning (regression from 3.4.1)
In the code that follows, gcc-3.4.1 says:
> gcc -W -Wall -Wno-unused-parameter qux.c -O2
qux.c:13: warning: variable 'x' might be clobbered by `longjmp' or `vfork'
gcc-4.0 with those same options gives no warning.
Note that neither version warns about 'sum' being clobbered.

[Bug c/19056] New: 4.0 optimizes away a SEGV; 3.4.1 does not
A minimized test case:
int main() {
int y = 1;
int *x = &y;
volatile int sum = 0;
while(1) {
sum += *x;
x++;
}
return 0;
}
Clearly, this should crash; under 3.4.1 it does. Under my checkout of a few
hours ago, however, it does not: instead, it enters an infinite loop (everything
inside the while(1) gets optimized away and we're left with just a jmp).
Workaround: make either x or sum volatile. This forces it to actually do the
computations inside the loop.
I'm not sure whether to view this as a compiler bug: this code is, at heart,
morally unbalanced. But it is a change in behaviour so I figured I'd report it.
