Actually, it turns out it's not ``reshuffling the heap'' that triggers
the bug, but rather the fact that when we call xmalloc, Emacs might
relocate buffer text.

IOW, I found the reason for the bug.  One of the callers of
load_charset_map_from_file maintains pointers into buffer text, so
when that gets relocated, ... you get the idea.

The first naive attempt to solve it was unsuccessful, so there's
probably something else at work here.  Hmm...
