Ah, okay, so it isn't an "obvious" bug after all. Mea culpa. I assumed it
was something GDB-ish because GDB 4.18 works...
With that in mind, I went and debugged this thing properly, and it seems
like my (redhat modified 2.2.12) kernel's ptrace is broken, specifically
when called from fetch_fpregs() in i386-linux-nat.c where it says:
ret = ptrace (PTRACE_GETFPREGS, tid, 0, (int) &fpregs);
I wonder how 4.18 managed to work.
