            Bug ID: 24844
           Summary: undefined reference to std::ios_base::failure::failure
           Product: clang
           Version: 3.7
          Hardware: PC
                OS: Windows XP
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs
          Assignee: unassignedclangbugs at nondot.org
          Reporter: daniel.f.starke at freenet.de

    Classification: Unclassified

Using Clang/LLVM 3.7.0 in combination with GCC 5.2.0 to compile a simple
application like this:
   #include <iostream>
   #include <string>

   int main() {
       std::string msg = "hello world";
       std::ios_base::failure f(msg);
       return 0;
   }
gives me the following error (it compiles without an error with g++):
2fb172.o:(.text+0xa7): undefined reference to
`std::ios_base::failure::failure(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)'

Reducing the pre-processed test case and comparing the assembly for the called
function gives
_ZNSt8ios_base7failureB5cxx11C1ERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
for GCC and
_ZNSt8ios_base7failureC1ERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEE
for Clang.
Or better readable...
GCC sees:
std::ios_base::failure[abi:cxx11]::cxx11(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)
Clang sees: std::ios_base::failure::failure(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)

I guess this might be due to the lacking support for __attribute__((__abi_tag__
("cxx11"))) in Clang.
