Looking at the equivilant in 3.51.02, I would guess the problem is hstmt
is null, as it will be if the connect has failed.


else if (henv){
error = my_SQLGetDiagRec(SQL_HANDLE_ENV,henv,1,szSqlState,
pfNativeError, szErrorMsg,
cbErrorMsgMax,pcbErrorMsg);
if(error == SQL_SUCCESS)
((ENV FAR*)henv)->error.message[0]='\0';
