Hello everybody
in a quiz I had a question about dangling pointer:
"What a dangling pointer is and the danger of using it"
My answer was:
"dangling pointer is a pointer that points to some area of ram that's
not reserved by the program. Accessing memory through such pointer is
likely to result in core dump (memory access violation)"

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
