It's probably something pretty strange: I built with ASAN, no MPS but my workaround for the hightlighting, and get an error: GC marks char-code-property-alist (staticpro), and hits a char-table object that is somehow broken. pdumper-object-p says yes for it, but when checking the mark bit of that char-table with pdumper_marked_p_impl, ASAN complains about an access outside of the bitset being used for the pdumper mark bits. (Not sure if that's already the loop I see without ASAN.) Didn't get further than that today. LLDB decided to crash as well at some point. I'm a bit out of ideas how to find out what's up with that char-table. Maybe I'll wait a bit until I have an idea how I could find that out.
