Tyler Hobbs resolved CASSANDRA-8351.
------------------------------------
Resolution: Fixed
I believe this has been (coincidentally) fixed by CASSANDRA-8225. I was able
to reproduce the issue against Cassandra 2.1.3, but the latest cassandra-2.1
does not reproduce. Although I'd like to understand the original reason for
the segfault, debugging threaded python applications in gdb is particularly
painful, so I'm not going to dig in any further.
I did notice one bug from 8225 relating to quoting column names, so I've opened
CASSANDRA-9080 to fix that.

> Project: Cassandra
> Issue Type: Bug
> Reporter: Joseph Chu
> Assignee: Tyler Hobbs
> Priority: Minor

> Running Cassandra 2.1.2 binary tarball on a single instance.
> Put together a script to try to reproduce this using data generated by

> Reproduction steps: Download files and run cqlsh -f stress.cql
> This may need to run a couple of times before errors are encountered. I've
> seen this work best when running after a fresh install.
> Errors seen:
> 1. Segmentation fault (core dumped)
> 2.
