      Description

      Observed in a stack trace, a crash here in parse_sql.cc:

      parser_state->m_lip.m_digest->m_digest_storage.m_charset_number= thd->charset()->number;
      

      Stack for reference:

      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;
