divide overflow

[Jason Schonberg]

The following code runs on a Sparc Solaris 2.6 system but fails with a "Floating 
exception (core dumped)" on an X86 Redhat 6.0 system.

Both systems were using egcs-1.1.2

_____
#include <limits.h>

int main()
{
 long int A, B, C;
 A = INT_MIN;
 B = -1;
 C = A/B;
}

I think the above has all the information needed to reproduce the problem.  I 
would be pleased to provide more information if you would find it useful.

Is this considered to be a bug in the compiler or a portability issue in user 
code?

Thanks.
