------- Comment #5 from phil dot sidler at attachmate dot com 2006-11-06 20:18 -------
Recreated with the following
#include <stdint.h>
main()
{
uint8_t area = 1;
uint8_t oldval;
uint8_t res;
oldval = area;
res = __sync_val_compare_and_swap(&area, oldval, 128);
}
Note that constant values less that 128 in the 3rd parameter work OK.
Casting the 3rd parameter to be unsigned does not work.
Using a temporary variable instead of a constant does work, but only with
optimization turned off.

I see you're right, this is probably fixed now.
This was on

thanks.

This is a dup of bug 28924 after all and has been fixed already.
