There was a problem hiding this comment.
I don't know if you need to protect against multi-threaded scenarios, but perhaps you should do an atomic exchange of the crash func pointer into a local variable while setting the static variable to NULL.

Needs some testing, but this should make application quits more graceful when running with an open console on Windows.
Closing the console or Ctrl+C-ing it will be treated the same as a forced termination via Task Manager
Ctrl+Break acts like a crash, because that's useful to have (Ctrl+C and Ctrl+Break events are when inputting to the console)
Shutdown will plainly exit the application since it shouldn't remain running, while logoff events will leave things down to Windows
