Certainly I cannot give Drew a snapshot from trunk built with
-DGC_MCHECK=1, because it will likely crash upon starting and, as Drew
doesn't run Emacs under GDB, he won't be able to provide us with more
information that "mcheck: memory clobbered before allocated block".

If you rebuild gmalloc.c with an added #define GC_MCHECK, do you see
the mabort calls too?
