Message        The identifier <name> from the pragma pack pop
                directive was not found on the top of the pragma pack
                stack.

 Description    The identifier specified in the #pragma pack (pop,
                <identifier>) directive was not found on the top of
                the pragma pack stack.  A previous #pragma pack pop
                or #pragma member_alignment restore may have already
                popped this identifier off the stack, the identifier
                may not have been previously pushed onto the stack,
                or extra elements are pushed on the stack on the top
                of element with the identifier, or the identifer may
                be spelled incorrectly.

 User Action    Check the spelling of the identifier.  Verify that
                the identifier was previously pushed onto the pack
                stack and not popped off by another #pragma pack pop
                or #pragma member_alignment restore, and all elements
                pushed on the top of the identifier are popped.
                Correct the directive(s).
