    Description

      MariaDB crashes with an assertion failure when executing a SELECT query containing a GROUP BY ... WITH ROLLUP clause combined with a HAVING condition. The failure occurs in Item::val_native() due to dereferencing a null Item pointer, leading to the assertion assert(0) at item.h:1606
