[Bug c/37560] New: bitfield not promoted to int

[clemens at ladisch dot de]

In the following program, the type of the assignment expression "f.x = 1"
should be int, according to the integer promotion rules.
However, gcc 4.xx (on all architectures I've tested) prints "1".


#include <stdio.h>
int main()
{
        struct foo { int x:1; } f;
        printf("%u\n", sizeof(f.x = 1));
        return 0;
}
