I was trying to look at https://gitlab.common-lisp.net/cmucl/cmucl/merge_requests/16 and gitlab responds with a 500 error. This was working before the merge happened. This merge request still works: https://gitlab.common-lisp.net/cmucl/cmucl/merge_requests/12 The only thing different that I can tell is that 12 was created by me and 16 was created by a contributor. Any ideas?
