Perhaps it's because you're casting the return value of a temporary object?  
I'm not sure on the exact behavior in C++ but what I think is happening is 
that you're destroying the QCString before the sqlite3_bind_text() call.  
Something like this:

  QCString utf8str = qsValue.utf8();
  int nRes = sqlite3_bind_text( mpVM, nParam, (const char*)utf8str.data(), -1, 
SQLITE_STATIC );
