[Maria-developers] Possibly a problem in "Allowed to use WITH clauses before SELECT in CREATE ... SELECT and INSERT ... SELECT"

Hello Igor, I was rebasing bb-10.2-compatibility on top of the latest 10.2 and noticed this grammar change:

create_select_query_specification: - SELECT_SYM create_select_part2 create_select_part3 create_select_part4 + SELECT_SYM opt_with_clause create_select_part2 create_select_part3 + create_select_part4 + { + Select->set_with_clause($2); + } ;

I have some questions: - From my understanding, opt_with_clause should go before SELECT_SYM Why does it go after? - Why this grammar change is not covered in tests? - What is the MDEV number for this change? Thanks!
