[Epoch 4.0p1 on an SGI IRIS under IRIX 4.0.1.]

I recall there being some discussion a while back about epoch crashing
and dumping core during a query-replace after several strings were
replaced.  I also thought somebody asked for copies of the victims
core files (or stack traces) to help track down the bug.  Was that
true?  Is this bug still a problem, or has it been fixed in 4.2?  (I'm
reluctant to change and rewrite my .el files given the \M- vs. \e-
debacle.)

I ask because it just happened to me -- luckily the autosave had
everything but the query-replace, which I repeated without incident.

To give you a taste, here's a bit from the dbx session.
Unfortunately, it was compiled with (MIPS) cc -O, not -g, so this
stack trace may be utter garbage.  (Well, its clearly garbage, but
maybe its not SUPPOSED to be garbage.)
