[bug #23039] gdnc crashes on OpenBSD/sparc64 on application connection

[Richard Frith-Macdonald]

Follow-up Comment #1, bug #23039 (project gnustep):

Most likely any sparc64 problems related to gdnc are to do with method
invocation/forwarding via ffcall.

I can try debugging it if you give me access to the box ...

I think the process would be to start gdnc, attach gdb to it, then start
something to connect to gdnc and wait for the crash.  If the stack is already
too corrupt to tell us anything at that point, we would have to set a
breakpoint somewhere in the NSConnection or NSPort code and catch the incoming
connection before it attempts to invoke the method on the loacl object, then
step through to see what's happening.

Of course, doing anything depends on you having a working copy of gdb which
can handle 64bit code.
