IMHO, the initial problem is that newline Emacs inserts where it shouldn't have; find the code which is guilty of that, and you've found your villain. The crash (actually, Emacs doesn't crash, it aborts itself) clearly shows that the display code found an impossible condition: a glyph row was not enabled. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://mail.gnu.org/mailman/listinfo/emacs-devel
