Comment (by Phyx-):

 Then I know what's going on, the `FreeConsole()` call that was there in
 the `cwrapper.c` before that broke under Windows 10 recently was detaching
 the caller from the console.

 I suspect now that this was done to now have the caller still handle
 signals. The issue was by putting it in `cwrapper` it broke in cases where
 the caller should handle it. such as when GHC calls GCC.

 So the call should actually be in `ghci.c` not in `cwrapper.c`, since here
 we *do* have an interactive session.
