Stack trace crashes with DLL

Open slipher opened this issue 5 months ago • 3 comments

With MSVC, if I enable the stack traces with USE_CPP23, run with DLL gamelogic, and do the command cgame.injectFault drop or cgame.injectFault exception or likewise with sgame, I get a crash inside the C runtime's stack trace machinery.

Yeah, I got that one too, though IIRC it did print the staktrace. Maybe it fails to stack unwind properly or something.

I expect you would have to be very lucky to get the full stacktrace due to the fully buffered logs...

Actually the problem happens on Linux too. And the stack trace code can still cause this crash even if the feature is disabled: it goes into mutual recursion between Sys::Drop and Log::Warn( "StackTrace unavailable: CPP23 required" ); until it hits a stack overflow. I assume the same thing also happens with logging an actual stack trace.
