Even though `read_bisect_terms()` is declared as assigning string constants, it in fact assigns allocated strings to the `read_bad` and `read_good` out parameters. The only callers of this function assign the result to global variables and thus don't have to free them in order to be leak-free. But that changes when executing the function multiple times because we'd then overwrite the previous value and thus make it unreachable. Fix the function signature and free the previous values. This leak is exposed by t0630, but plugging it does not make the whole test suite pass. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
