The other potential cause is code executed via LD_PRELOAD. If it allocates
memory using a different malloc (say, the libc malloc) that bash later
frees using its internal malloc, you'll get mismatches. You can tell that
by building bash --without-bash-malloc and seeing if you get the same
behavior.
