a very easy sample, only send the same 10 requests on a tcp session. Crash stack:

ViewController.m is very sample.

• (void)viewDidLoad

  for(int i=0; i<10; i++) {

      }
  

  }

  // Do any additional setup after loading the view, typically from a nib.
  }

@nanpoyhl, thanks for opening the issue. I'll see if I can reproduce this.

[nanpoyhl]

@goaway ,while i remove handler of SPDY by "[SPDYURLConnectionProtocol registerOrigin: reginfo];" everything is ok.

Do you still encounter this after 951317a?

Closing this as it strongly resembles the bug fixed in the above commit which is resolved and merged into master.
