--- Comment #24 from M W <mlwmohawk at gmail dot com> --- I know it is documented as "undefined," but it is also unexpected without even a warning. Anyone maintaining code and/or porting to rpi will simply not expect this behavior. I certainly didn't. I had been using my code for over a decade and the default casting did the "correct" (expected) thing across many different platforms. I'm really not sure how anyone is OK with this behavior. I'm concerned about the mountains of code out in the real world that may be failing silently. Now that the RaspberryPI is being used more and more as a drop in replacement for old x86 servers, this will impact a lot of people.
