FINAL RESULTS:

data/gtk-im-libthai-0.2.2/src/gtkimcontextthai.c:338:47:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
                                              strlen((char *) conv.conv));
