C++ compile error in stl_function.h: class member cannot be redeclared (binder1st) (in XCode 4.3.2)

binder1stCompileErrorXCode4.3

I came across this compile error in XCode 4.3.2: In stl_function.h:

      typename _Operation::result_type
      operator()(const typename _Operation::second_argument_type& __x) const
      { return op(value, __x); }

      // _GLIBCXX_RESOLVE_LIB_DEFECTS
      // 109.  Missing binders for non-const sequence elements
      typename _Operation::result_type
      operator()(typename _Operation::second_argument_type& __x) const   <--------- Class member cannot be redeclared
      { return op(value, __x); }

There is a difference between the two declarations. I thought that I was maybe using the wrong compiler, so I switched from Apple LLVM compiler 3.1 to LLVM GCC 4.2. This resulted in another set of compile errors that I was able to solve (my code did build). After that I switched back to the Apple compiler and wasn't even able to reproduce the problem!

Bottomline : this is not a bug in de STL library but a problem in my own code, LLVM GCC 4.2 gave me better clues than Apple LLVM compile in this case.

I hope this helps anyone puzzled by this odd compile error.

PS : this stl_function.h is in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/usr/include/c++/4.2.1/bits

I have also encountered the same problem.（in Xcode8.3.3)
But i didn't use STL.
