If something like this makes a difference then it means something has gone horribly wrong a long time ago. I haven't been able to reproduce this locally, but I'd recommend trying to set up some memory-allocation/thread-race checker and see what it produces.

@labath,

Yes, I even noticed what latest "fix" patch is just hint to fact what whole Process m_listener object looks like freed or unitialized memory - m_events collection size in Listener before crash happened looks invalid absolutely - random value, in my case about 8 millions events (!).

This looks about threads race condition, so still investigating - slow because bit bust with other issues, excuse me.
