[ros-users] weird node crash...

Hi all,
I have a really weird behaviour in rospy.
If I create a publisher to an existing topic of a custom C++ node, run
rospy.spin in a separate node, then do nothing and close the python
node, the C++ node crashes:
[shadowhand-5] process has died [pid 5903, exit code -11].
The simple code in python can be found here:

If I replace the publisher by a subscriber then my C++ node doesn't
crash. What's really weird is that my C++ node seems to be pretty stable
(I often kept it running for one day without any trouble). When I run
the C++ node in gdb then it doesn't crash...
Is there a call made to the node when a publisher to this node is deleted?
Any help greatly appreciated.
Cheers,
Ugo
