Might have been when they dropped some malloc hooks we were using, or
something like that.  IIRC this problem was "really fixed" with the
pdumper and before that we circumvented it by using the src/gmalloc.c
code during the dump (and switch to the native malloc afterwards).

So, you might want to try and tell Emacs to use src/gmalloc.c instead of
the system's malloc.
