[Bug: 21.4.17] Crash when using gnuclient

Dear Bug Team, I have found a reproducible bug which crashes xemacs-21.4.17 when trying to connect with gnuclient. I regularly use gnuclient when working at home to connect to my already running xemacs process at work, and this bug is preventing me from doing this, so I have reverted to using xemacs-21.4.15 for the time being, as that version is OK. To reproduce the bug: 1: Start xemacs (with or without -no-init-file or -no-site-file) 2: gnuserv-start 3: In a shell: gnuclient -nw (actually I normally use: screen -dmS xemacs_nw gnuclient -nw, so I can log off, and leave this window running in screen, but this is not necessary to reproduce the bug). 4: In the main xemacs X-window: delete-frame (leaving just the tty frame) 5: In another shell: gnuclient (displaying on the same or a different machine). This second gnuclient fails to open a window, and crashes xemacs. The crash only seems to occur if the tty frame is the only one open. If you have at least one X frame open, then it is possible to open another one with gnuclient. Also I was surprised to find this morning that I was able to attach to an xemacs process I had started from home on Saturday. I am not sure what is the significant difference in this case. My work PC is running an Exceed X server on Windows 2000, and my home PC is also running Exceed, but on Windows XP. Let me know if you need any further information about my X setup. Happy bug hunting!

Your files have been auto-saved. Use `M-x recover-session' to recover them. Your version of XEmacs was distributed with a PROBLEMS file that may describe your crash, and with luck a workaround. Please check it first, but do report the crash anyway. Please report this bug by invoking M-x report-emacs-bug, or by selecting `Send Bug Report' from the Help menu. If necessary, send ordinary email to `crashes(a)xemacs.org&#39;. *MAKE SURE* to include the XEmacs configuration from M-x describe-installation, or equivalently the file Installation in the top of the build tree. *Please* try *hard* to obtain a C stack backtrace; without it, we are unlikely to be able to analyze the problem. Locate the core file produced as a result of this crash (often called `core' or `core.<process-id>', and located in the directory in which you started XEmacs or your home directory), and type gdb /usr/local/bin/xemacs core then type `where' at the debugger prompt. No GDB on your system? You may have DBX, or XDB, or SDB. (Ask your system administrator if you need help.) If no core file was produced, enable them (often with `ulimit -c unlimited' in case of future recurrance of the crash.
