reduced testcase

+++ This bug was initially created as a clone of Bug #46873 +++

----- original.C -----
#include <map>
#include <string>

void foo()
{
    const std::string s;
    std::map<std::string, std::string>::value_type(s, s);
}
----------------------

Hopefully correctly reduced testcase is attached.
