            Bug ID: 21581
           Summary: libc++ iostream's bad() member function is returning
                    true, always
           Product: libc++
           Version: 3.4
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P

Created attachment 13352
  --> http://llvm.org/bugs/attachment.cgi?id=13352&action=edit
Source code plus binaries

So I compiled the code I have attached using the following flags:

clang++ -std=c++11 -std=libc++ -Wall -v *.cxx -o out_clang

The program compiles but it throws an exception immediately after I enter some
input (I do a check for istream.bad(), on romans.cxx). The weird thing is that
I also compile the code using g++ front end:

g++ -std=c++11 -Wall *.cxx -o out_gcc

And the code executes fine. I include the source code, plus the aforementioned
binaries I obtained from each call. I have gcc 4.9.2 and clang 3.6.

I checked the code with valgrind and it doesn't complaint on any of the
binaries.
