%destructor doesn't work without %union

[Ben Davis]

Hi,

 

Please CC all correspondence to me, since I am not on the list.

 

I have encountered a bug in Bison 1.875b. Specifically, I have found that %destructor fails when my code contains a #define YYSTYPE rather than a %union. The output contains the following line:

 

        { delete yyvaluep->(null); };

 

generated from the action { delete $$; }.

 

Apologies for not doing all the standard stuff like checking if it's fixed in CVS and attaching a minimal example that reproduces the problem. But I'm short on time, and it looks to me like a straightforward bug with an obvious cause! If you do need more information, let me know.
