[antlr-interest] CPP COMMENTS

[Henry Butowsky]

Hi Guys,
   Please help. I am at my wits end.

Im still trying to get C++ style comments working. I have the rule.

CPP_COMMENT: ("//" (~'\n')* '\n')
     { newline(); $setType(antlr::Token::SKIP); };


It seems to be crashing out in the lexer in CalcLexer::mCPP_COMMENT().
More specifically -- whats happening is that it is crashing out on the
line -- match('\n'). I've investigated with the debugger and whats 
happening is that it is matching everything from the comment start till 
the end of the file (ignoring any \n). Thus returning a -1 (which is EOF)

Setting codeGenBitsetTestThreshold to 999 ?
Setting k to 3,4,5 ?
Rebuilding antlr from scratch rather than using rpm distribution

Please help

Many thx Henry
