The QByteArray is assumed to contain an SQLTCHAR string (so, either UTF-8, UTF-16 or UTF-32-encoded). Only in the UTF-8 case would the size of the byte array be the same as the size of the SQLTCHAR string in codepoints, yet the size in bytes is what the code passed to the QVLA<SQLTCHAR> append() call, causing it to read past the QByteArray buffer in the UTF-16 and UTF-32 cases. Fix by properly calculating the string size from the size-in-bytes and then memcpy()ing into the QVLA. We use memcpy() and not QVLA::append(T*, n) because the QByteArray buffer need not be aligned on an alignof(SQLTCHAR) boundary (certainly not since it gained the prepend "optimization").
