Segmentation fault while running integration test.

[samarthg]

I have installed kafka (kafka_2.11-0.10.0.0), confluent-kafka-python and librdkafka properly.
If I run the integration test without testing consumer it works fine. However with "verify_consumer()" it fails with error Segmentation fault (core dumped)

What version (or git sha1) of librdkafka are you using?

Can you do this and provide the output?

$ rm core
$ ulimit -c unlimited
$ py.test tests/test_Consumer.py
# wait for it to crash
$ gdb python core
gdb> bt

Thanks

I think by 'integration test' OP means https://github.com/confluentinc/confluent-kafka-python/blob/master/examples/integration_test.py

I can reproduce the problem by specifying an 'on_commit' for the Consumer:
(Using confluent_kafka module version 0.9.1, librdkafka version 0.9.1, and Python 3.5.2)

from confluent_kafka import Consumer
def foo():
... pass
consumer = Consumer({'bootstrap.servers': 'localhost:9092', 'group.id': 'confluent-group','on_commit': foo, 'default.topic.config': { 'auto.offset.reset': 'smallest'}})

consumer.subscribe(["confluent-topic"])
msg = consumer.poll()
consumer.commit(msg, async=False)
Fatal Python error: PyEval_RestoreThread: NULL tstate

This was most likely fixed by this commit:
