commit 98f90d5547c9a69591cd24eb46f012ee96b2fa30

    sys-file-reader: Fix null deref on bad address@hidden attribute.
    
    When a variable had a bad address@hidden attribute, this was effectively 
read as
    an attribute without any values.  This is the only way to produce such an
    attribute.  The system file reader assumed that every attribute had at
    least one value and segfaulted if address@hidden did not.
    
    This commit fixes both the ultimate cause of the segfault, by dropping
    attributes with no values, and the proximate cause, by ignoring 
address@hidden
    attributes with no values.  Either fix by itself would be sufficient to
    avoid the segfault.
    
    Thanks to Tianxiao Gu for reporting the problem.
    Bug #54687.
