This happens when performance schema is enabled and a prepared statement is executed on a ColumnStore table. The fix is probably to do this in idb_vtable_process when parse_sql is called for COM_EXECUTE:
parent_locker= thd->m_statement_psi;
|
thd->m_statement_psi= NULL;
|
parse_sql(...)
|
thd->m_statement_psi= parent_locker;
