"Found unparseable version in RecommendedServerVersions" as a client
Do a git checkout main, build your Tor, run it as a default client, you get this message during startup
Nov 16 00:56:49.807 [warn] Found unparseable version in RecommendedServerVersions
I did a bit of gdb'ing and it looks like indeed my RecommendedServerVersions is NULL like the default
I did some git bisecting which led me to commit 6dfb4889, which in turn led to #40817 (closed) so I cc @trinity-1686a. Surprise! :)
Sounds like maybe that validate part should move on if the config entry isn't set.
