Could you try the attached patch?
According to the ODBC specification available at MSDN, then its possible for the SQLGetCursorName
function to point to a NULL name where the length and return codes still are correct, so if thats
the case it would fallback to the PHP cursor name which hopefully is the cause of this as I'm
unable to reproduce it
