Thanks, committed. There actually was no way to get a double free (the only
points where this label is used are before the free) but there was a usage of
the variable after free (invalid_blockalign label).

Thanks for spotting.

        Based on a patch by:
            Victor STINNER <victor dot stinner at haypocalc dot com>

        * gst/wavparse/gstwavparse.c: (gst_wavparse_stream_headers):
        Set variable to NULL after freeing it to prevent double frees
        or make failures by another use of it afterwards more obvious
        and fix use of it after the freeing.
