Nedit unstable after 1.7.0-56 update -- clipboard copy segfault

Nedit unstable after 1.7.0-56 update -- clipboard copy segfault

[Rob Gillen]

I'm not sure if this is a X11 issue or a cygwin update issue.  I'm
leaning toward the latter, but figured that I should start on this
list.

After updating my 1.7 installation to the latest cygwin DLL, my xterms
were finally able to exec bash (with some issues from bash as well),
but I immediately ran into segfault when copying to the clipboard from
nedit.  I.e. as soon as I highlighted a line of text and hit CTRL-C,
it dumped core.  The (probably mostly useless) stackdump:

-clipboard has been broken by Microsoft .NET sp1

[Duane Krings]

Microsoft's latest high priority update for .NET 3.5 SP1 for XP has broken the -clipboard option to XWin.
I have seen the following behavior on 2 PCs so far using cygwin 1.5:
   before the MS update all works fine
   after the update, any paste function in vim, or xterm, or wherever causes an immediate crash
   removing the -clipboard option to the XWin and everything works fine again (except of coarse copying between X and 
windows)

I am using Vista, and XWin -clipboard
I had, long ago already, to disable the 'Office Clipboard', which I did from
Outlook, by clicking away all the options.
It did not disable the 'clipboard' by any means: I can still happily
copy/paste between Windows (including Outlook) and cygwin (e.g. cat
/dev/clipboard).

Hi!

I am running "XWin -multiwindow" (without any other option), and nedit
still segfaults on pasting anything (even something copied from nedit
itself). I am attaching both coredump and cygcheck.out.

Kindly tell me if this is actually the same problem as described
before, because I am also having stability problems with vim.exe (not
gvim.exe, but vim.exe in xterm)

Regards,

Actually, this appears to be a known problem with lesstif (the Motif 
implementation which nedit and other programs use).  It looks like other 
distros may have a fix, but it will take me a little while until I can 
focus on this.

FWIW, if this is still in the pipeline...

I'm still on cygwin 1.5, but I experienced similar crashes witn nedit.
I don't remember that it crashed when hitting CTRL-C, but it crashes
most of the time if I hit CTRL-V to paste some text (sometimes it
works, though). The workaround is to use middle-mouse click to paste
(and maybe also the edit/paste menu).

I've encountered the same problem with copying to the clipboard within 
nedit. As a workaround, I downgraded to libXm2-0.95.0-2, as the problem 
does not appears to occur with this older version of the lesstif.

There is a patch to lesstif-0.95.2 described in 
http://sourceforge.net/tracker/?func=detail&aid=2846234&group_id=8596&atid=308596
Might this be the fix? (I don't have the knowledge to rebuild libXm2 
myself, so I'm unable to test the patch.)
