Hi,
I'm not sure I can provide something much more useful than the lame "it worked in a previous installation" -- that's why I consider downgrading. Here's what I can provide:
- My current cygwin is version 1.7.1-1, my Cygwin/X is 1.7.3.0
- I run 'XWin -multiwindow -clipboard -emulate3buttons'
- Then I use ssh to log into a remote Linux machine and start a konsole window
- From the konsole I start various applications all of which work fine except one
large company-owned application which crashes with a SIGSEGV
- Only the application crashes, the konsole and all other running remote apps continue to work
- The application works fine when I'm locally on the Linux machine I log into
- It also works fine when I use Xming (version 6.9.0.31) instead of Xwin,
but Xming has several other problems (e.g. clipboard)
- It also worked fine on my previous PC where I had cygwin 1.5.24 with Xwin 6.8.99.901
Unless someone can provide instructions how to find the rootcause for the SIGSEGV I would consider downgrading to something close to my older version and see if that helps. I already tried to downgrade just Xwin and downloaded XWin.20081204180806.exe.bz2 and XWin.20090629103603.exe.bz2 form ftp://cygwin.com/pub/cygwinx/ but that alone did not help. A colleague has the same problem, so it's not just my installation.
Is there an archive of old versions?
Regards,
Wolfram

Sad to say, this probably indicates a bug in your company application, so you
should report it to those responsible for maintaining it.
Even if the X server is returning something invalid, it could do something
more helpful, like exit with an error, rather than crash :-)

1. gdb --args your-mystery-application
2. Wait for the '(gdb)' prompt, type 'run'
3. Do whatever you do to make the crash happen. You should get another '(gdb)'
prompt, type 'bt full'
If the backtrace shows the crash is in a toolkit or X library, then this might
be worth addressing in the X server.

I'm sure it is a bug in the application but if people working locally on the workstation (the majority) don't experience it, pressure is low to fix it.

Thanks for the tip but that doesn't work in this case.

Found an archive of old cygwin versions here:

Thanks for your efforts, Jon!
