[21.5-b28] Assertion failed at search.c:1487

XEmacs consistently crashed when doing a yank in to an empty buffer which had flyspell and font-lock-prog-mode enabled. It didn't happen if I used "xemacs -vanilla". flyspell-version was 1.6h. XEmacs version was 21.5-b28 (+CVS-20070924). A web search highlighted a few other people who had crashes in similar places in search.c place, but with different backtraces. I didn't find a fix posted, so perhaps this extra information will be of use. ==== Fatal error: assertion failed, file search.c, line 1487, (this_pos) > ((Bytebpos) 1) && this_pos <= ((buf)->text->z + 0) Lisp backtrace follows: # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) search-backward("Local IspellDict: " nil t) # bind (end) # (unwind-protect ...) ispell-buffer-local-dict() ispell-accept-buffer-local-defs() # bind (buf) flyspell-accept-buffer-local-defs() # (unwind-protect ...) # bind (following) flyspell-word() # (unwind-protect ...) # (unwind-protect ...) # bind (command) flyspell-post-command-hook() # (unwind-protect ...) # (catch #<INTERNAL OBJECT (XEmacs bug?)
