--- Comment #1 from Drea Pinski <pinskia at gcc dot gnu.org> ---
This union:
union ln {
unsigned _BitInt(256) ln;
unsigned _BitInt(1) e[256];
};
Does not do what you think it does.
`unsigned _BitInt(1)` has 7bit padding.
So when you do:
l.e[5] = true;
l.e[4] = true;
l.e[2] = true;
l.e[7] = true;
l.e[20] = true;
l.e[30] = true;
l.e[60] = true;
l.e[77] = true;
It does not set bit 6, 4,2, etc. but rather 5*8, 4*8, 2*8, etc. bit of the
whole union.
