Looks good. The if-define-to-code ratio in LinuxDebuggerLocal.c is impressively high, in a bad way. An enhancement to cover cleaning it up sure wouldn’t hurt.

Yeah, I was on the fence here too, but don't want to risk more regressions. The "ifs" were rewritten i586 to get the "proper" macro, and the i386 fallback block is just for additional safety. I have not seen the failures on Mac due to ps_core.c, but it is better to be safe there as well. There is no 32-bit macOS build AFAIK. I don't quite understand the comment here: do you suggest to remove that block, or? I am leaning on capturing i586 everywhere i386 was captured before. That code is never built for 32-bit so neither i386 or i586 will ever be defined there. You can make the change but nothing will ever test it. Cheers, David Thanks, -Aleksey
