Bit 12 needs to be set in the protection register, not bit 44. The change has had three days testing on my rp3440 (PA8800) without any unusual segmentation faults. Also, tested on a couple of PA8700 machines. This fixes the problem noticed by Artem Alimarine. At the moment, I don't have a change for the macros. The DEP and DEPI macros conflict with PA 1.x mneumonics. So, they should be renamed. I also think the 32-bit instructions in the macros should use PA 1.x rather than 2.0 mneumonics. The 1.x mneumonics should be ok for both PA 1.x and 2.0. It is possible that building for a PA 1.x machine might not work with the current macros. Maybe James has something for the macros. Dave -- J.
