Sebastien SOILEN commented on AMQCPP-227:
-----------------------------------------
Hi!
I posted previously on the users ML for segmentation faults in the 2.2.4
version with APR resources.
Before opening new issue, I would check if my problem is related or not to this
one.
Here are the python code which causes the segfault:
{quote}
import sys
from pyactivemq import *
broker =
"tcp://127.0.0.1:61616?connection.closeTimeout=1000&connection.sendTimeout=5000&connection.socketBufferSize=128*1024"
def check_broker():
try:
f = pyactivemq.ActiveMQConnectionFactory(broker)
c = f.createConnection()
c.start()
c.stop()
c.close()
sys.exit(0)
except Exception, e:
sys.stderr.write("Erreur activeMQ: "+str(e))
sys.exit(1)
check_broker()
{quote}
Below are the complete traces of all the threads
Thank you.
Regards,
Sebastien SOILEN

> Mutex class allows for double free in APR pools under certain circumstances
> ---------------------------------------------------------------------------
>
> Key: AMQCPP-227
> URL: https://issues.apache.org/activemq/browse/AMQCPP-227
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Decaf
> Affects Versions: 2.2.4, 3.0
> Reporter: Timothy Bish
> Assignee: Timothy Bish
> Priority: Critical
> Fix For: 2.2.5, 3.0
>
> Original Estimate: 2 days
> Remaining Estimate: 2 days
>
> The Mutex class in the Decaf library can allow for two copies to be created
> which both share pointers to APR resources and when the second instance is
> destroyed a segfault occurs. The code needs to be correct to properly copy
> itself or prevent copying altogether so that this does not happen.
