21.5.13 crashing too while using c++, completions and font-lock

Hi folks. As reported earlier I had trouble with the SUSE 10.0 xemacs. A few days ago I downloaded the following: * xemacs-21.5.23.tar.gz * xemacs-sumo.tar.bz2 (latest version) The build (--with-xim=xlib --with-xfs --with-mule --with-debug) was done on the same machine running the same OS (SUSE 10.0). The .xemacs/custom.el is containing (load "completion") (load "font-lock") and .xemacs/init.el is empty Procedure: * open a file that triggers c++ mode (foo.cc for example) and contains a '#include' statement * goto the '#include' * goto the closing '>' and remove it SIGSEGV is the result for me. I can see the same behaviour having build it on a iBook G4 running Ubuntu 5.10 (There was a problem with /usr/X11R6/include/X11/bitmaps. I copied it from the SUSE machine. This made xemacs only running with '-nw' but the problems stays) Later on I've patched it to 21.5.24. The result was the same. The only thing I want to know is if anybody can reproduce this behaviour! Or if it's my fault.
