Sorry, I still don't know how to make much sense out of these crash
reports. Somebody else might be able to decipher it for you. (And I
would be interesting in hearing the translation process.)
I do have a couple of comments based on what you are saying though.
First, I probably should mention that GLUT is written on top of Cocoa
in OS X. So your compilation line might look like
gcc testprog.c -framework GLUT -framework OpenGL -framework Cocoa
The -lobjc is implicitly added by Cocoa for you. But since you managed
to get it to compile, this is probably not the issue. (Though you
might try it just to rule it out.)
Second, Cocoa accesses OS X's native windowing system, not X11. You
can launch a Cocoa application from the X11 terminal window, but it
will not necessarily be an X11 app.
If your code base has native X11 drawing functions, it probably will
not mix well with Cocoa. But the reason to use GLUT is so you don't
have to use any native windowing system calls (be it X11 or Cocoa).
But I don't know what's in your code base.
Finally, I would recommend you try running your program through a
debugger and see where the crash is occuring. Many times these crashes
are bugs in your application. Sometimes other platforms don't catch
bugs. I've had many instances where code worked fine on 2 or 3
platforms, but crashes on others because of subtle memory bugs in my
own code which didn't seem to bother certain systems. Or it could be
a branched code path within your library that just wasn't supposed to
be hit on OS X (like an X11 call).
Once you identify the offending block of code, people might be able to
help you better.

Thanks for your message. Here is the entire crash report. It says
"Backtrace not available". Why not? This GeoJasPer open source code
works fine under several versions of Unix, and Microsoft Windows.
Unfortunately, it produces a segmentation fault under Mac OS X. Any
comments would be greatly appreciated. The program is simply
trying to
display a TIFF or JPEG2000 image in an X11 window.
