The culprit may be memory troubles after Emacs exceeds its 8 MB
virtual memory limit.  You can increase this limit to 32MB with a
two line addition to src/config.h.

#define VALBITS 26
#define GCTYPEBITS 5

Probably not.

I thought that I was the only one who had this problem.  I thought it
had something to do with the fact that my machine runs Emacs version
18.55.0 because the Sys Admins haven't found time to upgrade it.

I just switched back to VM version 4.41 which doesn't have that
problem though I do miss some of the nice features of 5.31 like mail
buffers with unique names (as opposed to the default *mail* name),
and, the ability to mark multiple messages and run a command on all of
them.

Oh well!

-Ravi-

p.s. - I still don't understand.  Why is VM 5.31 the only package I
have tried that actually crashes emacs?  Surely it should have some
kind of protection built in.

   I am convinced that the culprit is VM. In particular, it appears that once
   your mail-files are sufficiently large (> 100 messages), then the tiniest
   network timeout sends emacs down the tubes. I am using VM 5.31.

   Does anybody else experience this problem

I experience it.

   and if so, how are you working around it.

I suffer with it.  I try to keep my mailboxes small, but that is
difficult.  Doing things with summary buffers that are re-ordered
seems to aggravate it.  Unfortunately re-compiling emacs is not an
option for me.  But I haven't given up VM.  Yet.

Not much I can do about the Emacs crashing phenom.  In the past I
have coded around known Emacs problems (like bugs in the regex
code) that caused crashes, but I can't do that here until the
problem is narrowed further.  All I can advise is to upgrade to
18.58 and if the problem persists start sending bug reports and
stack traces to bug-gnu-emacs@prep.ai.mit.edu.
