--- Comment #6 from paolo dot carlini at oracle dot com 2009-01-17 09:04 --- Maybe this issue isn't sufficiently clarified in the audit. Unless I'm badly mistaken (Jon, Chris will correct me), this is not a bug for a C++03 + TR1 bind (indeed the testcases provided by Doug are rather clear about that). Only in C++0x the specs say it must work. Of course implementations can also fix it for C++03 + TR1, but this is not in general the way we are managing these issues, we prefer leaving the TR1 version alone. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35569

And it should work if you do -std=c++0x, which I believe (from the title of the PR) is what the original intent was. W. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35569

I'm seeing the same thing with Boost.Bind (boost 1.37, GCC 4.2.1).
#include boost/bind.hpp
#include functional
using boost::bind;
using std::multiplies;
int main() {
// Fine.
int const lvalue = 5;
bind(multipliesint(),4,_1)(lvalue);
// Mistaken for a cast.
bind(multipliesint(),4,_1)(5);
}
