Description:
Run these queries:

CREATE TABLE t0 (c0 INT);
SELECT 1 FROM t0 HAVING 1 = ((SELECT 1) ORDER BY t0.c0);

The SELECT query will trigger an assertion error at sql/item.cc:8012
assert(context->query_block == thd->lex->current_query_block());

The compilation parameters are the same as issue 108148:

-DWITH_DEBUG=1 -DWITH_ASAN=ON -DWITH_UBSAN=ON and boost library version 1.77

How to repeat:
Run the queries above.

Hello Pedro Ferreira,
