Description Sami Farin 2015-11-30 22:47:27 UTC 
this magical function fails if first for(;;) loop 
succeeds in "tmp = Xmalloc(buf_size + data_len))"
and then succeeds in "name = _XimEncodeIMATTRIBUTE".

Then magical lines
    buf_s = (CARD16 *)&buf[XIM_HEADER_SIZE];
    buf_s[0] = im->private.proto.imid;
access free()d memory.  Assuming _XimEncodeIMATTRIBUTE sets ret_len to != 0.
