Bug#294878: xterm: segmentation fault NOT IN XawTreeForceLayout()

[Justin Pryzby <justinpryzby@users.sf.net>]

Package: xterm
Version: 4.3.0.dfsg.1-10
Severity: normal

I can consistently crash xterm.  Its not an exact dupe of #255749,
since a breakpoint at XawTreeForceLayout was never crossed, but it
gets SEGV anyway.

Steps to reproduce:
             open xterm on andromeda;
(in xterm)   ssh to cyberia
(on cyberia) cd iraf;
             ds9&
             cl;
             cl> tv
             cl> imedit
	     (press some alphabet keys, I don't know what they do, but
	     they're inputs to the imedit command); then,
	     h (apparently an undocumented imedit input) causes xterm
	     to SEGV with a stack smash.

IRAF is sufficiently obscure that people may have trouble reproducing
this (it may even be something wrong with IRAF, as well, since I'm
experimenting with it).  I can provide a shell account if necessary,
or strace something to see what inputs xterm is getting, if you tell
me how.

This may well involve the TEK window; I've never actually used imedit
before, so I don't know what its supposed to be doing:)

And I'll try to get more info on this somehow.
