I have no destructors. The parser I am generating is part of a compiler that never frees any resources (until it exits). Anyway, ParseARG_STORE is used once in lempar.c to actually store the extra argument and four times to suppress unused variable warnings (according to the source comments), so I guess a fifth time won't do much harm ;-) >> ./snl.c: In function ‘snlParser’: >> ./snl.c:2446:33: warning: comparison of distinct pointer types lacks a >> cast [enabled by default] >> while( yypParser->yytos >= &yypParser->yystack > > I think the latest trunk check-in may fix this. > https://www.sqlite.org/src/info/3a9d802fda105856 > > But that fix is untested, as the error handling logic where this code > is found is #ifdef-ed out in SQLite.

I don't know why I didn't see it when I looked at the repo today (I did intend to grab the latest version from the trunk), probably made a mistake navigating the web interface.
