Dear Xemacs maintainer, I forgot to indicate the following regarding the crash mentioned in my previous email. Just before the crash occurred, I was in a shell buffer with a program running and generating really a large amount of of output, so much that I interrupted the program. I then selected the whole content of the shell buffer (Ctrl-x h) with the intention of deleting it. I got an error message saying memory was exhausted. I then exited from the shell and killed the buffer. My attention was then put on some other window. When I wanted to go back to my Xemacs window, it was gone. The xterm window from which XEmacs had been started had output (instructions) regarding the crash. I followed the instructions to produce the stack backtrace below. Many many thanks. -- Laurent Langlois Software Developer Adacel Inc.

I am not the least concerned about this crash. However, I was able to get a stack backtrace. I had to trick 'dbx' just a bit to get it to provide the backtrace. Please find below an initial attempt at using 'dbx', then some shell commands and then the successfull attempt with the backtrace. Many thanks indeed. -- Laurent Langlois (Happy happy user of XEmacs and Emacs.) ________________________________________________________________________ ________ -> dbx /usr/local/bin/xemacs core Type 'help' for help.
