Newbie: Small program fails in "-d:release" but works with plain build

[Stefan_Salewski]

    name: r[i][0].strVal,
                    exportable: r.data(1, i).boolVal,
                    filename: r[i][2].strVal
    
    
    Run

You do access r[i][0] and similar elements without any checks if that elements 
exists. Generally debugging starts there is case of errors, and if I remember 
correctly the error message was matching to such an invalid acess. I can not 
test myself, I think I have not installed odbc and I have no experience with 
database access.
