I don't get any exceptions nor compile-time errors.
The application simply quits without further notice or warning. I
tried to catch this crash in WinDbg and I get memory access exceptions
(app is trying to access memory not belonging to itself). And
sometimes I even get INVALID INSTRUCTION exceptions (at OS level).
Here are a few other things I noticed:
- Sometimes the crash happens further down the stack (in a method
called by the really big method).
- I sometimes can't re-construct the crash if I step through the code
with the debugger (different stack?)
- Sometimes breakpoints work, sometimes they simply get ignored or the
app crashes before reaching them.
- The crash only occours on Windows. It doesn't matter if I compile
the code on Mac Intel or Windows itself using the IDE on Windows.
- I NEVER get any REALbasic exceptions or warnings.
- The application works just fine on Mac OS X - no crashes, nothing.
Does this sound familiar, or... am I on the right path?

Bastian
