------- Comment #1 from jakub at gcc dot gnu dot org  2010-07-06 09:25 -------
Shorter testcase:

extern void abort (void);

static char
foo (char si1, char si2)
{
  return si1 * si2;
}

int a = 0x105F61CA;

int
main (void)
{
  int b = 0x0332F5C8;
  if (foo (b, a) > 0)
    abort ();
  return 0;
}

Works with -O2 -fwrapv.
