commit 809a3a748d5f0cbaa0357ec63388ed291fb7b0bd Author: Nick Mathewson <nickm@torproject.org> Date: Sat Mar 30 21:07:15 2019 -0400 bug_occurred: a place where we assumed that "buf" was still a buffer In 9c132a5f9e87a2cd0f we replaced "buf" with a pointer and replaced one instance of snprintf with asprintf -- but there was still one snprintf left over, being crashy. Fixes bug 29967; bug not in any released Tor.
