Compiler fails on windows snapshot build SVN r237568 build off a command line
prompt build. I suspect this is magic static related as it compile fine if the
variable declaration is non static. 

Compiler error

PHI node entries do not match predecessors!
  %arraydestroy.elementPast = phi %"struct.std::pair"* [ %2, %3 ], [
%arraydestroy.element, %arraydestroy.body ], !dbg !303
label %arraydestroy.body
label %entry
fatal error: error in backend: Broken function found, compilation aborted!

Code 

#include <map>

void foobar(  )
{
    static std::map<std::string,std::string> mapping =
    {
        { "A", "Hello" },
        { "B", "World" }
    };
}
