I can reproduce the problem even when using cmake as recommended.

The problem is proton's fast and loose use of binary data in the
codec.  The assumption that a struct will be placed on the stack a
certain way falls apart in 64bit Visual Studio, so that it is no
longer OK to use either a single argument (pn_data_t struct) or two
separate ones (a size_t and char*), depending on what's convenient at
the time.  The va_arg macro works very differently in 32bit versus
64bit in this case.

I will have a work-around patch soon and will separately work an
official fix through review board and PROTON-488
