A simple program which crashes Wine but works on Windows.

The Wine MSVCRT _snprintf implementation is wrong; the simple test program to
be attached shortly is correct according to the docs from Microsoft, and works
fine on Windows, but under Wine (checked out recently from git), it crashes due
to heap corruption.
