Product:iOS SDK Product Version:7.0.3
Classification:Crash/Hang/Data Loss Reproducible:Always
 
Summary:
Under certain circumstances, a Multipeer advertiser crashes with `EXC_BREAKPOINT`. We're using `MCAdvertiserAssistant` and `MCBrowserViewController` but I found report that it's also happening when using a custom UI: http://stackoverflow.com/questions/19475366/multipeer-connectivity-crash-when-inviting-peer-that-stopped-advertising/19475506

Steps to Reproduce:
With two Peers, an advertiser and a peer browser:

1. Advertiser starts advertising
2. Browser sees the new peer
3. Advertiser stops advertising
4. In the time window before the stopped advertiser is removed from the browser's peer list, the browser sends an invite
5. Advertiser starts advertising again

Expected Results:
The invite to the old advertiser gets ignored

Actual Results:
`EXC_BREAKPOINT` on thread com.apple.NSNetServices.tcplistener-queue

Version:
iOS 7.0.3

Notes:


Configuration:
Occurs with:

iPhone 5 (32bit, iOS 7.0.3) <=> iOS Simulator (32bit, 7.0.3)
iPhone 5s (64bit, iOS 7.0.3) <=> iOS Simulator (32bit, 7.0.3)
iPhone 5s (64bit, iOS 7.0.3) <=> iPhone 5 (32bit, iOS 7.0.3)

(and probably all other configurations)
