 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:
