Bug ID: 21026
Summary: not1 + mem_fn does not work together
Product: libc++
Version: unspecified

OS: MacOS X
Status: NEW
Severity: normal

Hi,
While nesting algorithms and functor I stumble upon a code that does not
compile:
#include <functional>
#include <algorithm>
struct Test { bool pred() const { return true; } };
int main(int argc, char *argv[])
{
Test* t = nullptr;
// does not work: error: no matching function for call to object of type
'const std::__1::__mem_fn<bool (Test::*)() const>
auto f1 = std::not1(std::mem_fn(&Test::pred));
f1(t);
// works
auto f2 = std::not1(std::mem_fun(&Test::pred));
f2(t);
// works
auto f3 = std::not1(std::bind(&Test::pred, std::placeholders::_1));
f3(t);
}
Compiled with: clang++ -O0 -Wall -std=c++11 test.cpp on Mac OS X:
Apple LLVM version 6.0 (clang-600.0.54) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
Funny thing, with GCC, it is f3 which do not compile :)
Thanks,
