Right - but I don't see any `XFAIL` being removed from `TestCases/null_deref.cpp`, so to me it seems like that test was already being executed on Windows, with clang - this change just makes it work with MSVC too?

(I.e. in other word, this FIXME that you're removing was already ripe to be removed before this patch.)
