More details:

Windows 7, 64 bit, cmake 2.8.12.11 from cmake.org website.  DLL built
with gnatdll, import library built with MSVC's lib utility, static
library built with the MSVC tool chain.

I'll try to come up with a simple reproducer.  I hope to do this
completely with the MSVC tool chain as I don't expect people to jump
through the hoops of configuring cmake to use an Ada tool chain.
Unless Alan Irwin chimes in, that is.
