crttme.o comes from libgcc/config/darwin-crt-tm.c, which has:
/* Provide dummy functions to satisfy linkage for versions of the Darwin
tool-chain that that can't handle undefined weak refs at the link stage.
??? Define these dummy functions only when !HAVE_ELF_STYLE_WEAKREF. */
extern void *__cxa_allocate_exception (size_t) WEAK;
...
...
void *__cxa_allocate_exception (size_t s UNUSED) { return NULL; }
This looks like the NULL returning __cxa_allocate_exception that is causing all
this grief, and came from Patrick Marlier and Iain Sandoe's patch here:

Again, I'm a Darwin wimp. Anyone care to comment?
