Could you check what caused the breakage? It *may* have been the ptid
changes I made, or not.
2008-09-08 Pedro Alves <pedro@codesourcery.com>
Use ptid_t.tid to store thread ids instead of ptid_t.pid.
* gnu-nat.c (inf_validate_procs): If this is the first time we're
seeing a thread id, extend the main thread's ptid. If we still
have pending execs, don't be verbose about new threads.
(gnu_wait, gnu_resume, gnu_attach, gnu_thread_alive)
(gnu_pid_to_str, cur_thread, sig_thread_cmd): Adjust.
* i386gnu-nat.c (gnu_fetch_registers, gnu_store_registers):
Adjust.
If nothing obvious turns up, could you open up a bug report
with a testcase and instructions, please?
