it is a bug(or a feature) of flex! it happens when you have a very large 
token, check your sources, maybe it contains something wrong(like an 
unterminated comment or a too long string literal)

anyway, the new lexer, the one in the upcoming kdevelop 3 doesn't use flex! 
so, kdevelop 3 is not affected by this bug.
