I'll have to wait for Haroon for that info for the crashing builds he did,
but I've now reproduced it with:

Windows server 2012 R2, VS 2013 Community Update 5, cross compile tools for
x86 to amd64.  cl 18.00.40629 for x64, env:

  %comspec% /k  ""C:\Program Files (x86)\Microsoft Visual Studio
12.0\VC\vcvarsall.bat" x86_amd64"

"where cl" reports

  C:\Program Files (x86)\Microsoft Visual Studio

Note that cross compilation is a typical configuration on Windows, where
you routinely use 32bit x86 compilers to build 64bit code, except in the
newest SDKs.

I see the same symptoms, with the segfault.

This host is a clean install, an AWS instance created for the purpose.

It looks like woodlouse probably runs an older VS2013 and uses the native
x64 toolchain; its env includes:

  C:\\Program Files (x86)\\Microsoft Visual Studio 12.0\\VC\\BIN\\amd64

and does not have x86_amd64 in it.

BTW, I suggested to Haroon that he clone beta2 from git, then do a
git-bisect between beta1 (works) and beta2 (fails) to see if he can
identify the commit that causes things to start failing. I don't know how
far he got with that yesterday.

By comparison, I had no problems on the same host with VS Community 2015,
cl 19.00.23918, env "VS2015 x64 Native Tools Command Prompt":

   %comspec% /k ""C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\vcvarsall.bat"" amd64

On a side note I'm unable to build with vs2013 community u5 native tools (
for some reason. Link errors, unresolved external symbol _ischartype_l . cl
18.00.42629 for x64, env:

   %comspec% /k  ""C:\Program Files (x86)\Microsoft Visual Studio
12.0\VC\vcvarsall.bat" amd64"

"where cl" reports:

   C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64\cl.exe
