    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.
