src/external/gpl3/gdb/dist/gdb: nbsd-thread.c
Log Message:
When searching for an active thread (e.g. right after switching to threaded
mode), if no lwp is signaled, just stay with the current (inferior_ptid.lwp).
This fixes gdb -p to a threaded process with all threads active.
Previously we eroneously restored an lwp of 0 (returned as sentinel from
ptrace) to inferior_ptid.lwp, which then would not match any thread in
thread_list and caused assertion failures.
