--- Comment #1 from Phil Muldoon <pmuldoon at redhat dot com> ---
The actual failure occurs here in nat/x86-linux-dregs.c:68 on the system call:
ptrace (PTRACE_POKEUSER, tid, u_debugreg_offset (regnum), value);
if (errno != 0)
perror_with_name (_("Couldn't write debug register"));
The actual call is somewhere else, I believe, either with the values of the
arguments or some changed accounting in the kernel.
