gcc8-pr82600.patch
Untested fix. The problem is that the -Wreturn-local-addr implementation
requires full folding of the expressions such that it will actually not see
an ARRAY_REF if the corresponding DECL isn't an array, but a pointer.
Such folding isn't performed if processing_template_decl though (no folding is
done, cp_fully_fold just returns the passed argument immediately).
