I have a virtual function in a base class, which is then overwritten by a
function of the same name in a publically derived class. When I call the
function using a pointer to the derived class (ClassB* b; b->func(); ) the
base-class function is called instead of the new function in the derived
class. All other similar functions (virtual in the base class and
overwritten in the the derived class) work fine, it's just this one
function. ...

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.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
