Hi,
tried first to get working get_current_arch at the add_inferior_object time
but found it is probably right it does not work at that time.
gdb.server/server-run.exp currently crashes with:
thread.c:581: internal-error: is_thread_state: Assertion `tp' failed.
No regressions on {x86_64,x86_64-m32,i686}-fedora11-linux-gnu.
Thanks,
Jan
