So, I don't get the crash today, but also the bridge address is today accepting my connections. So I can actually get Tor to build a circuit and everything. This is in stegotorus-null.log.gz. I also tried against a server that sends a RST to try to simulate what happened yesterday, but it appears to be gracefully handled. That log is stegotorus-rst.log.gz. Sorry, I should have tried this again yesterday. Maybe I had a glibc version skew or something that resolved itself upon rebooting. David
