Description Ralph Loader 2006-11-03 07:32:51 UTC 
Description of problem:

The following program prints

128
-128

I believe that it should print 128 both times.
--------------------------
#include <stdio.h>

int main (int argc, const char ** argv)
{
    int a = 128;
    printf ("%d\n", (a & 0x80) ? 0x80 : 0);
    unsigned char b = 128;
    printf ("%d\n", (b & 0x80) ? 0x80 : 0);
    return 0;
}
--------------------------

Version-Release number of selected component (if applicable):

gcc-4.1.1-31

How reproducible:

Every time.
