Here is a problem I had with the Xemacs editor.
I was editing a file (named fgre_90c.e), then from the "Edit" menu
I selected the "find" button. A small window opened, and I entered
there the word for which I was looking. After finding a few instances
of this word (there were more instances in the file, but I did not
need to get them), I wanted to close this "find" window, so I pressed
"Cancel". The result was that the whole "xemacs" window disappeared.
Here is (the last) part of the text that appeared on the screen after
the crash:
Lisp backtrace follows:
delete-frame(#<x-frame "XEmacs" 0xb45>)

(lambda (image-instance event) (isearch-dehighlight) (delete-frame

[2] Segmentation fault xemacs fgre_90c.e (core dumped)
By the way, after this crash, using Xemacs again, I just used "ctrl-s"
to search for a string, and this worked normally.
