Package: gcc-3.4
Version: 3.4.2-2
Severity: important
gcc -ftrapv aborts 0 * (-1), e.g.
#include <stdio.h>
int main (void)
{
volatile int i = 0, j = -1;
printf ("%d", i * j);
return 0;
}
After a search on the GCC bugzilla, it is
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15526
which has been fixed.
This is important, because 0 * (-1) occurs so often (at least here)
that the -ftrapv option is currently almost useless.
