You're welcome :-)
Since the problem is only in the division, you can have an even
smaller testcase :
#include <stdio.h>
int main (void)
{
volatile long int n;
n = -2;
printf ("%ld\n", (-2147483647L - 1L) / (-n));
return 0;
}
The output gets the sign wrong in recent snapshots. Reported upstream
as #27116.
