When lvm2 command works with clvmd and uses locking in wrong way, it may 'leak' certain file descriptors in opened (incorrect) state. dev_cache_exit then destroys memory pool of cached devices, while _open_devices list in dev-io.c was still referencing them if they were still opened. Patch properly calls _close() function to 'self-heal' from this invalid state, but it will report internal error (so execution with abort_on_internal_error causes immediate death). On the normal 'execution', error is only reported, but memory state is corrected, and linked list is not referencing devices from released mempool.
