For bison, I believe the order of importance on this cleanup issue goes
like
this:
1. document cleanup behavior in the manual
2. make cleanup behavior consistent across YYABORT/YYERROR and all
skeletons
(I guess this means _no_ auto cleanup)
3. offer more cleanup flexibility (macros)
I agree.
I believe you and I are in agreement on how the first 2 points should be
resolved. Would one of the veteran bison developers like to offer words of
wisdom?
Paul, I just looked through the ChangeLog. I believe you committed the
patch that made YYABORT and YYACCEPT invoke RHS destructors.
In this thread, I've pointed out several reasons why I think this is
undesirable behavior. At the very least, it's inconsistent with glr.c.
What do you think about our proposed alternatives?
Joel
