I'm not sure that this is a gevent issue, so I'm posting it here. server.py 
sources are attached.

I should also say that this bug appears at first time, but it doesn't make it 
less scary. The packet that crashed python was the same as the one shown and 
I've already used this tiny server for a day or two without modifications, so 
it seems to me that this is not my mistake.

Ok, I've played with this some more and got some more segmenation faults. It 
looks like a gevent problem, but I think that python shouldn't completely fall 
so easy. Here is more traces:

Dmitry Groshev lambdadmi...@gmail.com added the comment:

I've changed gevent.wsgi server to gevent.pywsgi and it works as expected. Now 
I switched it back to gevent.wsgi and it doesn't crash too! That's strange, but 
I understand that you can't fix it without normal backtrace. I'm sorry for the 
inconvenience.
