Hello. I am porting a data visualization application from a
Windows200/Exceed and Unix/X11 Codebase to MacOS X. I know some of the
basics of X11 programming, but I have a whole lot to learn. I've been
doing a lot reading and I've got this (large) application pretty far
along, but I've run into a problem I don't know how to debug. The
application dies on a bus error during it's calle to XtRealizeWidget(),
the argument to which is the toplevel widget for the application. i'm
pasting the stack trace in below. Any help or resources you can point me
to that would help me debug this and future issuse would be greatly
appreciated.
