I actually don't know where the problem is.  I can't reproduce it in a
small snippet.  FWIW, this also works fine under mingw+wine:

  snprintf (buf, sizeof buf, "%5llums", t );

That is arguably more correct, but requires that all Windows supports

Something seems to go wrong when the 64-bit value is cast to a 32-bit
value and then passed as an argument.  The values are interesting, see:

MD5          27574050817572874ms 5083798169452554ms 5083798169452604ms

That isn't even close to 64-bit or 32-bit boundaries.
