It is curious that only MacOSX builds trigger an error about this, both GCC and Clang, but not Linux GCC nor Clang (see https://travis-ci.org/git/git/jobs/200182819#L1152 for details):

builtin/bisect--helper.c:299:6: error: variable 'good_syn' is used
		uninitialized whenever 'if' condition is true
		[-Werror,-Wsometimes-uninitialized]
        if (missing_good && !missing_bad && current_term &&
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
builtin/bisect--helper.c:350:7: note: uninitialized use occurs here
        if (!good_syn)
             ^~~~~~~~

If you "re-roll" (or, as pointed out at the Contributors' Summit, better put: if you send another iteration of the patch series), please squash this fix in.
