I hope someone understands what happens to my NSMutableArray.

I read records a, b, c, d from a database, load the fields into an object an add the object to an array. To do this I read the records into an instance of that object (tmpEvent) and add the Object to the target array (NSMutableArray myArray).

the code looks like:

for (condition) {
     tmpEvent.field1 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 0)];
     tmpEvent.field2 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 1)];
     tmpEvent.field3 = [NSString stringWithUTF8String:(char*)sqlite3_column_text(stmt, 2)];

     NSLog(@"myArray: adding %@", tmpEvent.field1);
     [myArray addObject:tmpEvent];
}

The NSLog shows

 myArray: adding a
 myArray: adding b
 myArray: adding c
 myArray: adding d

Subsequent I enumerate the array (this can be in the same or a different method):

for (myObject *records in myArray) {
    NSLog(@"iEvents  value %@", records.field1);
}

The NSLog now shows:

 myArray value d
 myArray value d
 myArray value d
 myArray value d

a mystery .... ??? any thoughts?
