The symptoms are those of a failure during conservative garbage collection, and my suspicion is that the conservative marking isn't picking up some register that's hiding in a setjmp buffer or whatnot. Suppose you do a "make clean" and then "make CPPFLAGS=-DGC_LISP_OBJECT_ALIGNMENT=2" and/or "make CPPFLAGS=-DGC_LISP_OBJECT_ALIGNMENT=1". Does that work around the problem? Likewise, suppose you do a "make clean" and then rebuild with compiler optimization disabled. Does that work around the problem? I'll CC: this to bug 10749, since GC_LISP_OBJECT_ALIGNMENT=1 may work around its problems too.
