Doing it right would involve running the test on Wine inside an
exception handler, and verify that it actually crashes. That's not
trivial to do in the tests though.

Also I'm concerned that adding a mechanism like this will encourage
writing tests that pass garbage pointers, since in most cases this
doesn't crash on Windows. But passing bad pointers isn't an
interesting test unless a real app depends on it, and if it does then
we have to prevent Wine from crashing, adding skip_wine in the test
won't help the app.
