duament opened a new issue, #134:
URL: https://github.com/apache/rocketmq-client-python/issues/134
I'm using rocketmq-client-python in a django project and have a Segmentation
fault issue.
Here's my `apps.py`,where a ready() function is defined to start a consumer.
```python
from django.apps import AppConfig
class AppConfig(AppConfig):
name = 'app'
verbose_name = 'app'
default_auto_field = 'django.db.models.BigAutoField'
def ready(self):
from rocketmq.client import PushConsumer, ConsumeStatus
def consumer_callback(msg):
print(555)
return ConsumeStatus.CONSUME_SUCCESS
consumer = PushConsumer('ocp5-consumer')
consumer.set_name_server_address('10.0.0.1:9876')
consumer.subscribe('OCP', consumer_callback)
consumer.start()
```
Then I got a Segmentation fault, the backtrace:
```
Thread 79 "ConsumeTP" received signal SIGSEGV, Segmentation fault.
