--- Comment #1 from blubban@gmail.com --- <zf_> strmbase is built against msvcrt rather than ucrtbase, which we actually specifically want, but modules that use it build against ucrtbase <zf_> and because vsnprintf is an export from msvcrt but not ucrtbase [for the latter it's inline and links to __stdio_common_vsprintf()], it then picks it up from ntdll, which it's also exported from
