Output of "ajo-gcc -v -w -m32 -Os -mno-push-args test512888621-reduced.c -c"
This reproduces for me with svn revision 172796 (2011-04-20), but it doesn't
reproduce with gcc-4.4. I'm on Ubuntu 10.10, x86-64. Attached "gcc-v.txt".
cat >test512888621-reduced.c <<EOF
extern long long ll;
extern int i;
void func_43(int, long long);
int func_35()
{
func_43(ll > 0x85, i);
return 0;
}
EOF
gcc -w -m32 -Os -mno-push-args test512888621-reduced.c -c
test512888621-reduced.c: In function âfunc_35â:
test512888621-reduced.c:8:1: internal compiler error: in df_refs_verify, at
df-scan.c:4267
This test case is reduced from the output of Csmith
(http://embed.cs.utah.edu/csmith/), using the following command line:
csmith --bitfields --packed-struct -s 512888621 > test512888621.c
