And curiously this > crash only happens after using Emacs for sometime. Is it possible to build Emacs with -fsanitize=address? This is further expounded upon in the GCC manual, and IME generally proves fruitful for such spasmodic bugs, since you can run Emacs with address sanitization enabled for extended periods of time as your "daily driver" (vis-a-vis tools such as Valgrind, which incur a prohibitive performance penalty).
