- Subject: [RFA] Don't use thread_db on corefiles
This patch fixes a really frustrating internal error when you open the
coredump of a multithreaded application. Depending on your kernel, either
the core has threads (corefile.c supports this just fine) or it doesn't.
Neither way will opening libthread_db work right.
This patch isn't quite complete, because strange things happen when you
connect to a remote target too. But fixing that requires a little more
Is this OK?
