commit 87ac4627260bc56825f1283a3a4d88b7f5e466d8
Author: Luboš Luňák <l.lunak at collabora.com>

    fix thread-unsafe return of a reference to a static
    
    The Mapping struct is small, so there's no need to reuse it.
    Without this, sc/qa/.../sumif_wildcards.fods sometimes fails with calc
    threading.
