--- Comment #21 from James K. Lowden <jklowden at gcc dot gnu.org> --- Commit 069bf2fe31e99f0415ddb6acaf76cfb6eee8bb6a on June 9 included a change to the lexer that corrected an uninitialized value for the SECTION token. That error could have manifested on Darwin and lay hidden otherwise. `make check-cobol` on Linux aarch64 reports success. If I am able to build gcc on Darwin I will `make cobol-check` there. Meanwhile please try it again. If the problem is not already resolved I will resolve it.
