Ok, this went on deaf ears... to illustrate, do the following:
------------------------- example.c ---------------------------
#include <stdio.h>
enum AAA
{
a = 0x1,
b = 0xFFFFFFFF, /* If this is > LONG_MAX we core dump */
};
int
main ()
{
unsigned int x = a;
printf ("x = 0x%x\n", x);
}
----------------------- end example.c -------------------------
% gcc -g example.c -o example
% gdb -nw example
(gdb) print a
Segmentation fault (core dumped)
