Parse error on functor wrapped with paranthesis

I found it. It is likely a variant of the known bug documented at
http://gcc.gnu.org/bugs.html#parsing

I need the paranthesis since my C++ code is synthesized from another
language. Having paranthesis ensures that operator precedence is preserved
during the translation. I will have to work around with things like
(0, std::less<int>()(10,20)).
