That's far of being a clear evidence. There are too many unknowns in your
hand we cannot see nor judge.

Can you please compile with your present compiler (into asm, with -S)
Johann's example and show the result here?


struct
{
    unsigned b0 :1;
    unsigned b1 :1;
    unsigned b2 :1;
    unsigned b3 :1;
    unsigned b4 :1;
    unsigned b5 :1;
    unsigned b6 :1;
    unsigned b7 :1;
} b;

void f1 (void)
{
    b.b7 = 1;
}
