swprintf requires a destination buffer size like snprintf. This was previously only working by chance because of how MSVC emits variadic functions. swprintf also automatically appends a null terminator to the output string so there's no reason to add it via the format string. This was leading to a buffer overflow and occasional heap corruption.
