Functions virshSecretEventNameCompleter, virshPoolEventNameCompleter, virshNodedevEventNameCompleter allocates only enough space for array of N strings. However these are null terminated strings, so program needs to alloc space for array of N+1 strings. How to replicate error: valgrind virsh, use completer for '-nodedev-event --event' or '-pool-event --event' or '-secret-event --event'.
