I've been using lemon as the parser generator for ETL (http://etl.i-want-a-pony.com/) an open source C based template language, and we've been running into some problems with recent versions. The first problem is in revision 1.17 of lempar.c. You removed an if( yymajor==0 ) return; from Parse, which appears to be necessary for the final Parse(pParser, 0, sToken) line in the lemon examples (from http://www.hwaci.com/sw/lemon/lemon.html), which we've been following in ETL. Putting that line back keeps things from segfaulting. If it's more correct to not have that final Parse call I can simply remove it, but for now I've been sticking with the documentation.
There are a few other problems we've been hitting (specifically, something in 1.34 and 1.35 of lemon.c appears to make our parser totally not work), but since I haven't had time to figure out if that's something we've done wrong I figured I'd hold off on worrying about that and just let you know about the lempar.c problem. Sorry if there is a more appropriate forum for this kind of question, lemon itself doesn't seem to have a dedicated mailing list, so this seemed like the next best thing. Thanks, -garrett
