looks like you found the problem.  when I make the following change as
you suggested, the bug is eliminated:

#define DECODE_COMPOSITION_END(c1)                                      \
  do {                                                                  \
    if (! COMPOSING_P (coding)) /*(coding->composing == COMPOSITION_DISABLED)*/ 
                \
      {                                                                 \
        *dst++ = ISO_CODE_ESC;                                          \
.
