VS 2015 compile error: parser stack overflow, program too complex

[tommyettinger]

I'm not sure what to paste here, especially since I've since gotten MoarVM to build with VS 2013, but when compiling with Visual Studio 2015 Community RC's 32-bit or 64-bit cl.exe on Windows 7, I get this particularly unusual error after successfully configuring and building much of MoarVM, but before it gets to nmake:
src\strings\unicode.c(45034): fatal error C1026: parser stack overflow, program too complex
I can try to get more information if needed; is there a verbose output flag I can use to get any information you'd need? It's especially strange that it works perfectly, all tests passing, with 2013 but breaks only on 2015.
