        <pre>I'm getting error message if I try to compile code below using LLVM-vs2014 in
Visual Studio 2015:

#include <regex>
int main()
{
    std::regex test("test");
}

Error message:
1>CL : fatal error : error in backend: symbol
'?id@?$collate@D@std@@2V0locale@2@A' can not be undefined

In Visual Studio 2015 with LLVM-vs2014 the same code compiles properly.

For tests I used most recent installer from <a href="http://llvm.org/builds/">http://llvm.org/builds/</a>:
LLVM-3.9.0-r272572-win32.exe</pre>
