Re: xemacs crash
Hi,
Sorry for having reported this bug though mentioned in the PROBLEMS file.
I've got a question, however. As I've mentioned before, this does not
happen when I start xemacs with a -vanila option; or for that matter,
when I use the key sequences mentioned in my previous mail. If this was
caused purely due to a bug in the motif libraries, then, I presume this
should occur regardless of how I start / use xemacs.
Why then, is this occuring only when init.el is read?
Regards,
Arvind.

Two notes on Motif bugs from PROBLEMS. Unfortunately, you seem to
have the incurable one.

Motif delete-device crash:

has been reported to solve the problem on Solaris 2.7:

For information (although they have not been confirmed to work), the
equivalent patches for Solaris 2.8 are:
108940-33 108652-25

Or maybe the HashTableForEachItem crash (says "Linux/Lesstif", but has
been observed on Solaris and HP/UX; no known cure for those platforms):

** Linux
*** XEmacs crashes on exit.
This is known to happen with Lesstif version 0.93.36. It is
apparently due to breakage in Lesstif. There is a patch for Lesstif.
Frank McIngvale <frankm(a)hiwaay.net> says:
Ok, 0.93.34 works, and I tracked down the crash to a section
marked "experimental" in 0.93.36. Patch attached, "works for me".
