With all fixes in, Emacs 24 can run the tests for an the Org compiled by Emacs 22 now with just one error remaining, on master this is: Test ob-exp/mixed-blocks-with-exports-both condition: (wrong-type-argument number-or-marker-p nil) FAILED 19/403 ob-exp/mixed-blocks-with-exports-both and this one on maint: Test test-org-src/blank-line-block condition: (error "No special environment to edit here") FAILED 346/378 test-org-src/blank-line-block One of the 13 errors when Emacs 22 runs the testsuite itself is due to an unconditional use of visual-line-mode, which Emacs 22 does not have.
