I have reported and this is FIXED in cvs of openmotif 2.3.0 (better way
than my solution below).
There is at least one more nedit crash issue related to motif that was
solved in the motif cvs.
I have the feeling that openmotif 2.3.1 is not far away since almost all
known bugs have
been fixed. Nedit has been very stable.
Thanks

So it's Motif. Unfortunately we are not connected to that project and
can't forward the bug. At least one of the Motif guys is reading our list
however, so he will already know the problem and the proposed solution.
Thanks!

Sammy, nice job on diagnosing this. I've been chasing this bug for a
while and trying to develop a workaround.

The crash is happening in line 3655 of List.c in motif 2.3.0:
Program received signal SIGSEGV, Segmentation fault.
0x00002aaaaaba9ef8 in ReplaceItem (lw=0x9d7f40, item=0x9e4090, pos=1) at
List.c:3655
3655 if(lw->list.selectedPositions[i]==pos+1) {
I am not a c programmer (fortran) but I looked into the motif source and
added
few checks (same check is used below in List.c) and it no longer crashes
on 64bit.
Here is the motif patch I used. Please let me know if this makes sense and
in that
case file as motif bug:

If I build the executable with static link (make linux-static) on i386
(redhat 7.3), nedit doesn't crash even when I run it on x86_64 (redhat
enterprise linux 4).

It is not crashing on i386 but it is on x86_64. I build nedit on both
platforms and the 64 bit version is crashing.
As an additional note, I am using latest motif-2.3.0 including few new
patches from cvs. The previous user was using 2.2.4 so it probably is
not a motif issue.

the executable was build on a 32-bit machine but was running on a 64-bit
machine. I tried to run nedit the the machine on which it was build, and it
didn't crash.
