I added a special case/workaround for self-referential DW_AT_containing_type attributes (commit 0a1e1b on mjw/dwarf_output branch). And that seems to "solve" the issue. At least there are no other reference chain cycles in the make check self tests. So for now I hope to just continue with the current algorithm setup and regard this one as just a weird case that shouldn't happen. I do see dwarfcmp-test failures and crashes though. These might indicate that dwarf_output is creating bogus trees (or at least ones that dwarfcmp cannot proof equal to the original). Looking into that.
