Posted by developer: Fixed as of the upcoming 8.0.2 release, and here's the changelog entry: An assertion was raised when a create function at server bootstrap attempted to evaluate non-resolved expressions.
Description: Server bootstrap is invoking Item_func_get_system_var::val_int() without having resolved the expression in advance. The first such call occurs during the execution of the following statement: CREATE DEFINER='mysql.sys'@'localhost' FUNCTION ps_thread_stack ... How to repeat: Add an assertion, and observe a crash during to bootstrap, in ./mtr main.1st diff --git a/sql/item_func.cc b/sql/item_func.cc index 03644cf..f3f5c1d 100644 --- a/sql/item_func.cc +++ b/sql/item_func.cc @@ -7644,6 +7644,7 @@ do { \ longlong Item_func_get_system_var::val_int() { THD *thd= current_thd; + DBUG_ASSERT(fixed); if (cache_present && thd->query_id == used_query_id) { Suggested fix: Add the assertion, and fix any assertion failures.
