--- Comment #1 from Mark Wielaard <mark at klomp dot org> ---
libdw dwarf_attr_integrate does prevent cycles by limiting the chain of
DW_AT_abstract_origin and DW_AT_specification to 16 (arbitrary number).

On a different level, DW_AT_import can also create cycles (or rather infinite
imports). __libdw_visit_scopes does contain some cycle detection.
