1-2. When I use Objective-C on Mac OS X, the first thing I do when I start developing an Application is to install an UnhandledException handler that gives me a full stack trace when it catches an unhandled exception. I would very much like to do this on Ubuntu using Foundation (GnuStepBase) since everytime NSObject catches a doesNotUnderstandSelector my App aborts and I have to bugger around for 10 minutes with the debugger to find out the selector, class and method. I have tried installing an unhandled exception handler using the ( mostly ) undocumented functions to no avail. All the functions I install never get invoked. Does anyone know how to do this with certainty.

Certainly ... to the best of my knowledge this is exactly the same mechanism in gustep-base as in the Apple Foundation.
This feature has always been present in base.

At present the handler is set via a macro in the released versions of base (though it's a function in MacOS-X).
In subversion trunk I changed that.
