I asked an earlier question, which got off-topic in CString and Unicode issues.
I\'ve now reduced my example to namespace std and cout (instead

At Slava's insistence, I worked with ctors to find an easy fix:

#include 
#include 
#include 

struct Params
{
    int         inputType;
    std::string moduleName;
    Params(const int n, const std::string& s) :
        inputType(n),
        moduleName(s)
    { }
};

int main()
{
    std::map options = {
        { "Add",       Params(30, "RecordLib" ) },
        { "Open",      Params(40, "ViewLib"   ) },
        { "Close",     Params(50, "EditLib"   ) },
        { "Inventory", Params(60, "ControlLib") },
        { "Report",    Params(70, "ReportLib" ) }
    };

    for (const auto& pair : options)
    {
        std::cout << "Entry: " << pair.first << " ==> { " << pair.second.moduleName << "    }" << std::endl;
    }

    return 0;
}

However, the original code should have worked, and apparently is an acknowledged bug by Microsoft.
