It's an far too old problem. And as far as I remember, there
are different locations in the code causing it.

One place I remember well. It's in the tcop mainloop in
PostgresMain(). The querytree list is malloc()'ed (there and
in the parser) and free()'d after the query is processed -
except the processing of the queries bails out with elog().
In that case it never runs over the free() because the
longjmp() kick's it back to the beginning of the loop.
