[PATCH] detaching and threaded linux apps
- From: Liam Stewart <liams at redhat dot com>
- To: gdb-patches at sources dot redhat dot com
- Date: Mon, 3 Jun 2002 14:36:35 -0400
- Subject: [PATCH] detaching and threaded linux apps
thread_db_detach and lin_lwp_detach don't remove their target operation
structures from the target list when a detach on a threaded application
is done. This leads to the failure of the num_lwps == 1 assertion if a
gdb user (for some reason) detaches again before starting/attaching to a
new inferior.

* lin-lwp.c (lin_lwp_detach): Remove target operation structure
from target stack after detach operations are done.
* thread-db.c (thread_db_detach): Ditto.
