Program Options MacOS Error

Hi All,

I was trying to use boost program options to capture a std::string like 
the examples in the documentation. However I keep getting the error:

libc++abi.dylib: terminating with uncaught exception of type 
boost::wrapexcept<boost::bad_any_cast>

when i try to retrieve the value from the valuemap, i.e. 
vm["source"].as<std::string>();

The code that I have (which right now is essentially the tutorial 
example) runs fine on linux but has the above error on macos.

Am i doing something wrong or is this a genuine platform specific bug?

Sincerely,

--Michael
