Maybe it's pointer guarding. Try setting LD_POINTER_GUARD=3D0 in the environment when building Emacs.

Unfort= unately there are still ~1000 differing bytes left.
Is it possibl= e to determine the source address in temacs/bootstrap-emacs from the positi= on in the ,bss segment? Then maybe we could figure out which data is actual= ly nondeterministic.
