It crashed again. This time the slot pointed to was again in
Fgarbage_collect, but it was 80(sp). That's where the variable
message_p (char) is stored. The value of message_p is 0,
but it happens that the low 8 bits of the address of clear-temporary-map
are zero, so storing the value of message_p into that byte didn't
alter the pointer in the word.
What seems fishy here is that clear-temporary-map still points to
that vectorlike even though the vectorlike has been freed.
Maybe that's where the real bug is. Why didn't this code
#if GC_MARK_STACK
symbol_free_list->function = Vdead;
#endif
prevent the problem?
