Re: fatal error during isearch-forward

Hi! I encountered a fatal error during an isearch-forward within a several 10000 lines buffer. Eventually it turned out that "size does not matter": I was able to boil the problem down to a mere 3-bytes buffer containing the letters "IAI". If you place point just before the 'A', and then do a "C-s C-w" sequence, xemacs dies from: Fatal error: assertion failed, file search.c, line 1487, (this_pos) > ((Bytebpos) 1) && this_pos <= ((buf)->text->z + 0) instead of marking the "AI". This occurs for example in today's cvs-head. To be more precise, the assertion triggers for CVS date-tag "-D 2007-08-27" and later, while it does not for "-D 2007-08-26" Among the few files changed in that interval, it turned out that revision 1.9 of "lisp/mule/latin.el" causes the problem (or maybe makes an older problem evident). I built my version of xemacs --with-mule. Find below my system info (saw the same effect on a redhat system as well, with the same build configuration). regards, Klaus ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: Linux linux 2.6.11.4-21.17-default #1 Fri Apr 6 08:42:34 UTC 2007 i686 athlon i386 GNU/Linux configure '--with-package-path=/home/klr/xemacs/lib/xemacs/xemacs-packages:/home/klr/xemacs/lib/xemacs/mule-packages' '--infodir=/home/klr/xemacs/xemacs-21.5/info' '--with-infopath=/home/klr/xemacs/xemacs-packages:/home/klr/xemacs/mule-packages' '--with-athena=3d' '--with-xpm' '--with-png' '--with-jpeg' '--with-tiff' '--with-gif' '--with-mule' '--with-gpm=yes' '--with-sound=native' '--with-pop' '--with-clash-detection' '--with-canna=yes' '--with-wnn=yes' '--with-xim=xlib' '--with-database=no' '--with-postgresql=no' '--with-ldap=no' '--with-hesiod=no' '--with-widgets=athena' '--with-menubars=lucid' '--with-scrollbars=lucid' '--with-dialogs=athena' '--with-msw=no' '--with-optimization' '--with-cflags-debugging=' XEmacs 21.5-b28 "fuki" (+CVS-20071118) configured for `i686-pc-linux'.
