Hopefully you are crashing after the call to exit ... I forced a non-standard link to use "C"-only startup files (eliminated some of the constructor stuff) *and* turned off free'ing at exit time (eliminating all destructor stuff) by using a blackhole __free_hook. If you are using the old GNU malloc included with XEmacs or the system malloc supports (the equivalent of) __free_hook, you should be able to do the same thing. See the code that references `voodoo_free_hook' in src/emacs.c.
