Works for me on a Debian system with a clean 7.5a8. Have you tried with a fresh bundle as well?

Another user on #tor today confirmed that snowflake on Linux with Tor Browser 7.5a8 worked around a Tor block done by the local university.

For what its worth, I am also unable to reproduce this. I tried on an Ubuntu 14.04.5 system with a Tor Browser that was upgraded from 7.5a6 to 7.5a8.

I wonder if snowflake-client is crashing or refusing to start, and why.

The issue seems to be reproducible per the info provided in duplicate #25087 (moved).

After the gcc update, snowflake-client is still linked to libatomic.so.1, so it seems it didn't solve the issue.

Moving remaining tickets to May.
