This looks like a double free somewhere in the remove() method in the HashTable implementation, maybe in the lower level code for the linked lists which are used for buckets. I'd be happy to look into this later today or next week.

Oooh another __cxa_finalize crash. Points towards global destructors (hopefully not in malloc again :) ).

muscar commented 4 years ago

@ADKaster is there a previous issue around this I can have a look at?

ADKaster commented 4 years ago

LibGUI global destructors: https://github.com/SerenityOS/serenity/issues/900 Sergey fixing a hack I put in for global destructors in malloc.cpp https://github.com/SerenityOS/serenity/pull/1240

ADKaster commented 4 years ago

The solution is probably to add AK::NeverDestroyed wrappers around some global hash map of RefCounted objects

muscar commented 4 years ago

Thanks, I'll have a look.
