Re: [mythtv] Re: Re: SIGSEGV at end of recording
Can you put something like: printf(deleting refsock: %p\n, this); in the 'if (refCount 0)' clause in server.h? Also, something like: printf(new socket: %p\n, this); in the constructor, and printf(locking socket %p\n, this); in the Lock + unlock functions (change text as appropriate, of course). Don't really understand how it could be crashing, really. Things shouldn't be able to be deleted and still stay in that list, unless.. This isn't a slave backend doing the dying, is it?
