[seed] Append user data to the new arguments array, not the source one

    Append user data to the new arguments array, not the source one
    
    This code was previously adding a new item to the passed in array
    instead of appending it to the newly created array, causing a buffer
    overflow that sometimes ends in stack corruption and a crash.
