Hi,
Do you run by any chance a 32-bit only machine? This could explain the
crash, the compiler has still 32-bit problems. This will be fixed in
the final 0.5 release.

I was following the (admittedly quite old) page covering this sort
of activity at http://www.macruby.org/trac/wiki/MacRubyFromObjC.
My main.m and rb_main.rb are vanilla and copied from the FlickrDemo
(which runs on my system). If I reduce rb_main.rb to the bare
minimum of the following, I still get the error.
framework 'Cocoa'
NSApplicationMain(0, nil)
I'm assuming it's something in my ObjC code that is causing the
problem -- is there a good way to zero in on it? My llvm and
MacRuby knowledge is pretty rough, so I'm not sure where to drop
breakpoints. If there's a "don't use <datatype>" rule of thumb,
that would be great, too, as that appears to be where things may be
hung up.
Thanks!
