See Feedback Report 12072: REALbasic crashes when C++ raises exception in out of memory situation
REALbasic does not handle exceptions on the c++ new operator, so your app crashes. I hate this. I'd prefer if they catch this c++ exception and raise an OutOfMemoryException (which they prepared earlier when they had memory).
Today I added a plugin method InstallSystemExceptionHandlerMBS. If you call it, it will wait in background and whenever your app crashes, it will show a message. The last message before your app dies, but it's better than nothing. This works currently on Mac OS X and Linux, but not on Windows.
