I've been trying to work on a library that allows Haskell to call into .Net code, but there's a major show stopper in that the .Net runtime starting with version 4.0, doesn't like the executable files that GHC produces.

I've managed to reduce a test case to not actually depend on using Haskell, but just using GHC to compile a C file, and that C file being nothing but a dumb wrapper around a small dll. The resulting executable exhibits the incorrect behaviour:

> stack exec ghc -- main.c -no-hs-main
> main
1
2
3
4
5
6
ICLRRuntimeHost Start failed w/hr 0x80004005

Then I can also use GCC on the intermediate object file that was created, and produce an executable that exhibits the correct behaviour:

> stack exec gcc -- main.o -o main2.exe
> main2
1
2
3
4
5
6
7
8

I've put a copy of the test case here: https://gitlab.com/tim-m89/DotNetHostingTest
