    Fix crash on startup
    
    The last three keys were removed in
    66a34214ea4a5cab3d9762e084c2968addf93aff so we need to iterate 9 times
    instead of 12.
    
    Also, the current code is triggering -Waggressive-loop-optimizations so
    let's fix the data type to avoid undefined behavior.
