Thanks for putting in the ticket, I never noticed the original mailing
list post back in December. I read the explanation of the problem
referred to in the original December post, however it seems to me the
bug is in optional's safe-bool implementation under c++11. That is,
the expression "max==false" should implicitly convert the optional
"max" to a boolean and compile.
