      Description

      Replication steps

      1. Add a new Memcached instance (use localhost and leave other defaults)
      2. Map the default Application cache to Memcached
      3. Go to front page
      4. Go to the cache administration page

      Expected

      • Both pages are accessible

      Actual

      • The cache administration page segfaults.

      I am happy to provide more information to reproduce this, but I could not figure out what would cause the segfault.
