commit b3e80fce17f04cf7c83ef3843d2de0cc3bfef389
Author: Karsten Loesing <karsten.loesing at gmx.net>
Date:   Fri May 3 09:28:06 2019 +0200

    Fix unknown issue with spread() function.
    
    This is a hotfix to work around the issue described in #30351.
    Hopefully, we'll come up with a better fix that doesn't go backwards
    from tidyr to reshape2.
