[sqlite] I think lemon bug

[Jong-young Park]

Hi all.

I want to use "Lemon" parser generator for my own project because of
multi-threading.
But I find the strange bug.

I made sample calculator program for testing.
See the part of grammar file :

expr(X) ::= expr(A) PLUS NUM(B) .
{
       X = A+B;
       printf("plus-result : %d\n",X);
}

After execute lemon, that changed like this:

#line 19 "cal.y"
{
       yygotominor.yy4 = yymsp[-2].minor.yy4+yymsp[0].minor.yy0;
       printf("plus-result : 0d\n",yygotominor.yy4);
}

'%' changed to '0'!

I don't analyze lemon source yet. But I think it's about parsng directive.
Or, is there another technique that I don't know? At least, not in lemon
document. :)

I used lemon in sqlite-3.3.6 source archive.
If Somebody who give me advice or fix it, I'll glad.


Thanks.
