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).
