barche
I had to recompile and refactor my project because the argument for
constructorwas changed to require a finalizer policy instead of a boolean. I replaced everytruewithjlcxx::finalize_policy::yes, otherwise it would fail to compile, see below for the compiler error.After recompiling the project, it now crashes without an error message on exit:
The stacktrace doesn't point to any line of my own code, as far as I can see, how would I go about finding out how to fix this?
