If possible, can you generate a backtrace. Of course, in your case,
I guess it's gonna be tricky as you didn't compile with debug enabled.

For other reasons, I also have to compile QtHandles in release mode,
that is, I need to link it against release versions of Qt libs. However,
I still want to compile QtHandles itself with debug enabled and that's
the reason of all the win32-specific tricky things in common.pri
(use debug flags in release qmake variables)

If you manage to do something similar for mac, you might be able
to generate a useful backtrace.

I tried replaced the debug libs you've linked to with the Qt debug lib I have (libQtUiTools_debug.dylib), but I get many undefined symbols ...

$ make

Perhaps there are other libs I need to link to? What I have for Qt libs is ...

$ ls -1 /opt/local/lib/libQt*[a-z].dylib

/opt/local/lib/libQt3Support.dylib

/opt/local/lib/libQtCLucene.dylib

... or maybe there are some developers libs that I don't have installed. I'll experiment with other package options from MacPorts and see what I can find.
