That is so embarrasing! They teach this in the nursery school :/
By coincidence, I've spent at least half an hour today on finding the
memory overwrite elsewhere, which turned out to be caused by the bug above.
The buffer overrun comment refers to something else - I'm not sure if
WideCharToMultiByte will produce single byte character string for ANSI
codepages. If it produced a real multibyte string, it could exceed the
buffer supplied by the application.
