I simplified the code and could reproduce the bug with:

void test (void)
{
  int i;
  for(i = 2; i >= 0; i--)
    {
      volatile int j = 0;
    }
}

with "gcc -O2 -ftrapv". This is Debian bug 405065, which I reported
almost a year ago (but that was long enough that I didn't remember
it), and PR29534. This is annoying that this bug hadn't been fixed
for etch.
