--- Comment #2 from Ben Woodard <woodard at redhat dot com> ---
With the trunk version of libabigail this appears to be a slightly different
bug. It asserts rather than crashes. With the trunk version abidw doesn't segv
when processing /lib64/libclang-cpp.so.11
abidw: ../../../libabigail/src/abg-dwarf-reader.cc:13223: void
abigail::dwarf_reader::finish_member_function_reading(Dwarf_Die*, const
function_decl_sptr&, const class_or_union_sptr&,
abigail::dwarf_reader::read_context&): Assertion `__abg_cond__' failed.
Program received signal SIGABRT, Aborted.
