commit 3b3217087ecdc7a51bfeba5233e1a4612da9ea5b
Author: Bernhard M. Wiedemann <bwiedemann@suse.de>
Date:   Thu Dec 27 11:24:43 2018 +0100

Avoid recursion depth variations across builds
    
    See https://reproducible-builds.org/ for why this is good.
    
    Variations are likely coming from ASLR.
    
    On an openSUSE Linux system, this changed
    $Storable::recursion_limit
    from varying between 14265 and 14267 to a constant 14256
    
    There could be a chance for remaining variations.
    
    --- 
    Better fixes welcome.
