commit 5b8956df3b3bc4593c0372703cfb07d75b4fc15e Author: Nick Mathewson <nickm@torproject.org> Date: Mon Aug 28 10:11:49 2017 -0400 In test_establish_intro_wrong_purpose, use tt_i64_op on ssize_t Since ssize_t is signed and might be 64 bits, we should use tt_i64_op to make sure it's positive. Otherwise, if it is negative, and we use tt_u64_op, we'll be treating it as a uint64_t, and we won't detect negative values. This fixes CID 1416338 and 1416339.
