--- Comment #1 from Damjan Jovanovic <damjan.jov at gmail.com> ---
Adding author to CC.

The calling app does:

    hCVxD = CreateFileA(argv[1], 0,0,0,
                        CREATE_NEW, FILE_FLAG_DELETE_ON_CLOSE, 0);

Possibly because CreateFileA() calls file_name_AtoW() with alloc==FALSE, which
uses NtCurrentTeb()->StaticUnicodeString, which FIXME() might use too?

But then why is the ELF build unaffected?
