  o Minor bugfixes (crash on exit):
    - Avoid a set of possible code paths that could use try to use freed memory
      in routerlist_free() while Tor was exiting.  Fixes bug 31003; bugfix on
      0.1.2.2-alpha.
Set 'routerlist' global to NULL before freeing it. There is other code that uses this value, and some of it is apparently reachable from inside router_dir_info_changed(), which routerlist_free() apparently calls. (ouch!) This is a minimal fix to try to resolve the issue without causing other problems. Fixes bug 31003. I'm calling this a bugfix on 0.1.2.2-alpha, where the call to router_dir_info_changed() was added to routerlist_free(). 2019-07-19 15:49:52 +02:00			`o Minor bugfixes (crash on exit):`
