Back when Intel introduced the 80286, they didn't quite document everything right away. Errata were needed. Then the 80386 changed things. And then someone convinced them to add just one more feature at the last minute, which didn't get documented properly again.

The History of a Security Hole takes a look at the problems introduced by the I/O Permission Bitmap (IOPB) in the 80286, and how fallout from the implementation caused a security hole in all versions of OpenBSD up to 6.3 and NetBSD up to 4.4.

Conclusion? This programming thing is hard.

    The Free Pascal [freepascal.org] people had a front end for Delphi in their compiler, and it's cross platform.

    I asked the developer of the BGB emulator about Free Pascal and Lazarus, and he said it doesn't support all the GUI/VCL stuff that BGB uses.
