RFA: Patch for corefile support
- From: "J. Johnston" <jjohnstn at redhat dot com>

- Subject: RFA: Patch for corefile support
- Organization: Red Hat Inc.
The attached patch fixes a problem in gdb when a corefile is read in
after a multithreaded application has been debugged. What happens is that
the thread-db and lin-lwp layers are still around and run into internal
errors.
The solution is simply to unpush the thread-db ops in its mourn_inferior
routine. If a corefile gets loaded, there is no thread-db to interfere.
If another multi-threaded app gets loaded, the thread_db_new_objfile is
designed to bring back the thread-db layer as needed.
This fix solves another failure in the killed.exp testsuite as well.
Ok to commit?
