Hi,
Running "make check" I get the following, dropping most of the
begining since it seems sensible enough. Apparently this should show
if FFI works on Windows?
I noticed that your test results didn't include failures for
Sparc.hs/Callback.hs/Sin.hs. After more investigation, I found that
these tests only fail when Windows Data Execution Prevention (DEP) [1]
is enabled. When I disable DEP for hugs.exe, these tests pass; when I
enabled DEP then the tests fail. So, apparently the code that builds
the thunks used for callbacks does not correctly set the
executable/non-writable flags on the thunk after it is created. There
was a very similar bug in GHCi/runghc that was fixed just a few weeks
ago.
I think the solution to this problem is probably simple for somebody
familiar with the GHCi solution, or somebody familiar with the Windows
memory management API's. But, failing a fix, we should at least note
this problem in the release notes, and the installer should
automatically disable DEP for hugs.exe, runhugs.exe, and WinHugs.exe.
