================================================================ Dear Bug Team! I had several crashes, which happened while I was using VM and editing a file in HTML mode in a different frame. I was also using gnuclient to open the new frames. I could not reproduce the bug systematically, although it did hit me several times. Sadly I can't get a C stack trace, since when I run gdb on any of the cores, it gives me the following error, and then crashes itself :( Program terminated with signal 6, Abort trap. Dwarf Error: Cannot find referent at offset 506. (gdb) where zsh: segmentation fault (core dumped) gdb `which xemacs` xemacs-21.4.14.core I guess without that info, there's not much that can be done about it. If I can get more info (repro steps or a C stack trace), I'll submit another report. Thanks for XEmacs, I love it. Anyway, here are two lisp backtraces from different crashes: ========== Backtrace 1 ========================================= get-buffer-window(#<buffer "*SGML LOG*"> visible) # bind (name limit on-frame not-this-window-p buffer) get-frame-for-buffer-noselect(#<buffer "*SGML LOG*"> nil nil) # bind (shrink-to-fit on-frame not-this-window-p buffer) get-frame-for-buffer(#<buffer "*SGML LOG*"> nil nil nil) # bind (window old-frame target-frame explicit-frame) byte-code("..."
