Hmm... was this run before, after, or during GC ?
[ I assume it was before. ]
Can you use the mem_find to try and figure out whether it's pointing at a
GC-managed block or not?
Can you also disable the block-release code (the one that calls xfree on
blocks of cnos cells and lisp_misc objects) to see if it is maybe pointing
to blocks that have been reclaimed?
