--- Comment #1 from Nathaniel Shead <nshead at gcc dot gnu.org> --- Created attachment 61747 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=61747&action=edit possible fix Sorry for the breakage. The issue is this assertion in assemble_name_resolve: mark_referenced (id); ultimate_transparent_alias_target (&id); if (id != id_orig) name = IDENTIFIER_POINTER (id); gcc_assert (! TREE_CHAIN (id)); With my change, not just IDENTIFIER_TRANSPARENT_ALIAS identifiers can have TREE_CHAINs. It appears that perhaps only platforms with ASM_OUTPUT_WEAKREF undefined will run into this. Unfortunately I don't really have much capacity to look into this for the next few weeks, but I imagine something like the attached patch may work. (And adding some other assertions to validate that my assumption that a IDENTIFIER_INTERNAL_P will never be a transparent alias.) At some point I can try building a cross-compiler to verify, but otherwise please feel free to submit (a version of) this patch if it resolves the issue.
