From: Julien Grall <[email protected]>The function lu_close_dump_state() will use talloc_asprintf() without checking whether the allocation succeeded. In the unlikely case we are out of memory, we would dereference a NULL pointer. As we already computed the filename in lu_get_dump_state(), we can store the name in the lu_dump_state. This is avoiding to deal with memory file in the close path and also reduce the risk to use the different filename.
