            Bug ID: 17819
           Summary: packaged_task cannot be built from an lvalue of
                    function type
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: hhinnant at apple.com
          Reporter: kariya_mitsuru at hotmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified

The following code cannot be compiled with clang and libc++ r193963:

#include <future>

void f() {}

int main()
{
    std::packaged_task<void()> task(f);
}


According to C++ standards(ISO/IEC 14882-2011) §30.9.6.1 p2, it seems that this
code should be compiled successfully.
