google-cloud-ruby: ssl_transport_security.c "Corruption detected" failure on GKE

I just added the stackdriver gem to my Rails app running on Docker in Google Container Engine (GKE).

I have done no additional installations or configuration, just require the Stackdiver gem. Attempting to log a message produces the following error:

irb(main):001:0> Rails.logger.info "blah"

I’ve just upgraded to the latest Stackdriver gem (was at 0.8.0 before and attempting to log would segfault the Ruby process, so this is an improvement).

    stackdriver (0.10.0)
      google-cloud-debugger (~> 0.28.0)
      google-cloud-error_reporting (~> 0.27.0)
      google-cloud-logging (~> 1.2)
      google-cloud-trace (~> 0.27.0)

I’m investigating as we speak and realize that the issue is quite possibly in an underlying library but I’m pressed for time and need to get logging working so I’m posting here in hopes someone has knowledge or ideas they can shared.

Thanks, Neil.
