First off, I apologize if this gets long. I'm simply trying to give you all
enough information to help me out. I'm writing (almost finished, actually),

hi everybody,
I need to clear something out,
does anybody have ever encountered such an exception until now :
"Un unhandled exception of type System.NullReferenceException occurred in
system.windows.forms.dll
Additional information: Object reference not set to an instance of an
object."
I receive this exception when I use HelpProvider and play a little with the
question mark upon different controls.

g++-12 -std=c++20 -Wnarrowing bit_field.cpp
