--- Comment #18 from David Binderman <dcb314 at hotmail dot com> ---
Part way through reduction, the C code seems to be
int crc32_tab_0;
int crc32_context = 0xFFFFFFFFUL;
void main(int , char []) {
{
int crc;
int i;
i = 0;
for (; i < 256; i++)
crc32_tab_0 = crc;
{
{ crc32_context = 0 ^ crc32_tab_0; }
}
printf("...checksum after hashing %s : %lX\n", "g_50",
crc32_context ^ 0xFFFFFFFFUL);
}
}
This looks to me like reading rubbish off the local variable stack in main
and then hashing it.
AFAIK not a bug in gcc, but may be a bug in csmith.
