I am encountering a really frustrating bug that occurs only on certain conditions:
- OSX (no problem on Windows) - I am using 10.7 with XCode 4.63 and the latest JUCE tip.
- application compiled in Release mode with link time optimizations enabled => PITA to debug
- application is executed as 64bit (if I tick the 32bit flag in the executables properties, everything works fine).
So whenever I run the app under those conditions and open a modal window (I know evil, but I want the native FileChooser) my application crashes.
This is the report:

It looks like there is something really weird going on. However, the JUCE demo app does work, which makes me totally angry, since I am doing nothing else than opening the file chooser.
Has anybody a clue what this could be?
