`dotnet.exe msbuild` exits code 1 even if MSBuild succeeds

Steps to reproduce

So far, this only reproduces on our Windows 2012 R2 machines, but it is consistent. I can get you access to a machine to investigate more.

We are trying to upgrade ASP.NET Core to build with the 2.1.300-preview3-008646 SDK. Previously we were building with 2.1.300-preview2-008530. https://github.com/aspnet/BuildTools/commit/ed5ca9de3c652347dbb0158a9a65eff3471d2114

Expected behavior

Exit code 0 when a build completes

Actual behavior

dotnet.exe exits code 1, even though MSBuild succeeds.

I ran a build with MSBUILDDISABLENODEREUSE=1 last night, but it failed with the same problem. 😕

@rainersigwald I’ll send you a link to the internal server that is failing.
