If you had included this before (or perhaps noted that I specified Win32
API, not general C function) then I wouldn't have raised the CWString
issue. This declaration is not Win32 API and the original CString was
correct for it.

If you're still having issues... does this by any chance have any
association with threads? ghci uses the threaded runtime *and* handles
threads slightly differently from compiled code with -threaded (if it core
dumps in ghci with -no-ghci-sandbox then this may be the issue)?
