For LOCK view is opened but not prepared thus leaving 'table' field set to NULL. invalidate_locked_for_write() wasn't checking that and call to invalidate_table(NULL) crashes server. To invalidate_locked_for_write() added check that ensures that table is completely opened. sql/sql_cache.cc: Fix bug #13424 locking view with query cache enabled crashes server Added check that table is completely opened. mysql-test/t/view_query_cache.test: Test case for bug#13424 locking view with query cache enabled crashes server mysql-test/r/view_query_cache.result: Test case for bug#13424 locking view with query cache enabled crashes server
