I can't reproduce the problem on my bigendian 32-bit host
(Solaris 10, 32-bit sparc, Sun C 5.12 2011/11/16),
so the problem can't be just the 32-bit bigendianness.

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.
