            Bug ID: 18721
           Summary: std::bind() seems to not pass placeholder arguments
                    correctly when they are repeated
           Product: clang
           Version: 3.3
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

Created attachment 12005
  --> http://llvm.org/bugs/attachment.cgi?id=12005&action=edit
Code that demonstrates the bug

Please see attached file chk.cc. I compiled the file using clang++ as follows:
  clang++ -std=c++11 chk.cc -o chk

I then ran it. Got the output:

0xdd5048
0


I was expecting to see pointers that got printed out as being non-NULL -
however, one of them is NULL. Something to do with the std::bind()
implementation.
