Looks likepcalways has an even value in GDB on the FX3, so I guess the current behavior is fine. Though, I should probably support all the mode-banked registers as well, that's currently not implemented. Sadly there's no way to get a good register index↔name linking afaik, so time...
Stack walking – which produces the stack trace – can also fail. In that case you'll likely see a single valid frame, then a small number of bogus addresses. If symbols or stacks are too badly broken to make sense of the stack trace, then there are usually ways to fix it: ...
