commit 934e47958c78d1184beaaefdf3baefd3eecbea05
Author: Eike Rathke <er...@redhat.com>

    Resolves: tdf#94869 propagate error when obtaining a scalar double value
    
    ... if any operation like popping a value or calculating an intersection
    resulted in error, so the error gets passed as double error to matrix
    operations where one operand is a scalar value.
