This is probably an issue with libtooltipmenu. If you click the back arrow to close the menu, then attempt to open the menu again, this crash to console doesn't happen. Using 'Esc' even once to close the menu will eventually lead to a crash.

This crash also occurs with gzArchipelago's inventory menu.

I can't repro this in gzdoom, so this is probably a result of changes in the menu code in uzdoom, which means I'll be able to start debugging it when uzdoom lands in nixpkgs unstable.
