Most likely you need to remove the try .. catch block. As currently nobody
is really using MSVC 2015 we are not going to see these issues. So if you
plan to compile with MSVC 2015 you must fix most of them yourself until we
finally switch.

I have currently no MSVC 2015 to see if removing the try catch block is the
right fix.

Regards,
Markus
