Snapshot 20010112 goes wrong and it's definately the flag --with-cpu=opteron that causes the trouble.

[Bug tree-optimization/30858] [4.3 Regression] ice for legal code with -O2 -ftree-vectorize
--- Comment #7 from dcb314 at hotmail dot com 2007-02-21 12:17 --- (In reply to comment #6) proposed patches - http://gcc.gnu.org/ml/gcc-patches/2007-02/msg01734.html would you mind giving these patches a try? (to see what's the next ICE...?) If the patches have been applied to gcc mainstream, then they will appear in the next 4.3 snapshot, due 23 Feb, and so I will test them then. Is this acceptable ? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30858

[Bug c/55791] New: gcc fails to detect wrong type in sizeof in malloc
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55791
Bug #: 55791
Summary: gcc fails to detect wrong type in sizeof in malloc
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: dcb...@hotmail.com
Given the following code, culled from customer code,
# include stdlib.h
extern void g(char *);
void f()
{
char *p;
// wrong type in sizeof in malloc
p = (char *) malloc( 10 * sizeof( char *));
g(p);
}
gcc can't detect that the malloc line should be something closer to
p = (char *) malloc( 10 * sizeof( char));
i.e. the type in the sizeof expression must be the same as (or
at very least the same size as) the type of destination buffer.

I've been trying to bootstrap using -g -O3 in BOOT_CFLAGS. That doesn't work, but -g -O2 of course does. After trying out all the flags individually that make the difference from -O2 to -O3, it is the -fipa-cp-clone flag that is the only one that breaks bootstrap. The rest of the flags are fine. On trunk snapshot of 20130130, I get ../../src/trunk/gcc/c/c-parser.c: In function ‘c_expr c_parser_postfix_expression_after_primary(c_parser*, location_t, c_expr)’: ../../src/trunk/gcc/c/c-parser.c:6908:16: error: ‘origtypes’ may be used uninitialized in this function [-Werror=maybe-uninitialized] origtypes); ^ This looks a false positive to me.

[Bug c/54582] New: gap in FORTIFY checking of buffer lengths
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54582
Bug #: 54582
Summary: gap in FORTIFY checking of buffer lengths
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: dcb...@hotmail.com
Consider the following code
# include stdio.h
void f(int n)
{
char buf[2];
sprintf(buf, ab%d, n);
printf(%s\n, buf);
sprintf(buf, ab);
printf(%s\n, buf);
}
int
main()
{
f(2);
return 0;
}
compiled as
[dcb@zippy Alphasrc]$ ~/gcc/trunk/results/bin/gcc -g -O2 -Wall
-D_FORTIFY_SOURCE=2 -c sep14a.c
In file included from /usr/include/stdio.h:936:0,
from sep14a.c:2:
In function ‘sprintf’,
inlined from ‘f’ at sep14a.c:11:9:
/usr/include/bits/stdio2.h:34:3: warning: call to __builtin___sprintf_chk will
always overflow destination buffer [enabled by default]
return __builtin___sprintf_chk (__s, __USE_FORTIFY_LEVEL - 1,
^
so gcc can find the problem in the 2nd sprintf, but not the first.
All the numeric specifiers (%d, %u etc) all produce at least one
character, so gcc could take account of this in checking buffer lengths.
Here is cppcheck finding the problem
Checking sep14a.c...
[sep14a.c:8]: (error) Buffer is accessed out of bounds.
[sep14a.c:11]: (error) Buffer is accessed out of bounds.
