When a TreeCtrl is redrawn and items have images set (using ImageList), it causes a crash on OS X. The same code works
correctly on Linux.
Looks like the underlying wxBitmap is broken or has got GC'd somewhere...
The (snipped) backtrace is:
Program received signal EXC_BAD_ACCESS, Could not access memory.
