--- Comment #10 from Will Cohen <wcohen at redhat dot com> ---
That example in comment #5 at [0x0000000000000055, 0x0000000000000055) looks
different than the original example as it is referring to an argument for an
inlined function.  The function mentioned in the original description
static_protections is declared as inlined but is actually generated as an
non-inlined function.

Would https://dwarfstd.org/ShowIssue.php?issue=170427.1  apply in the original
example?  Are there actual multiple views of the parameters in the places with
0-length location list entries?

The first 0-length location list entry for prot would be 

        .byte   0x4
        .uleb128 .LVL615-.LVL615
        .uleb128 .LVL615-.LVL615
        .uleb128 0x1
        .byte   0x55

The second 0-length location list entry in the location list would be:

        .byte   0x4
        .uleb128 .LVL637-.LVL615
        .uleb128 .LHOTE19-.LVL615
        .uleb128 0x1
        .byte   0x52
