--- Comment #16 from Dan Kegel dank@kegel.com 2008-01-03 18:07:25 --- That's not what I was suggesting. wineserver is a plain old unix app, you can run it directly using wineserver -k gdb wineserver -f and then, in another windows, run the app that dies. If you're lucky, gdb will catch the wineserver abort.
