I think it's related to the /GX or /EHsc compiler options.
IIRC ATL 3 project wizards turn this options off by default (at
the very least in the Min Dependency config)

The easiest thing would be to compile with C++ exceptions
support turned on. Please note, though, that this requires the
CRT.

Otherwise you're supposed to provide an implementation of
boost::throw_exception.

You could just terminate or raise a structured exception with
Windows' RaiseException API. No unwinding happens in the
latter case (that is object with automatic storage duration won't
have their dtors called).
