Could you check what caused the breakage? It *may* have been the ptid changes I made, or not. 2008-09-08 Pedro Alves <[EMAIL PROTECTED]> 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? -- Pedro Alves
