Bug #3275

Updated by Junxiao Shi about 9 years ago

Steps We are trying to reproduce: 

 1. construct `Fib` and `Measurements` attached use a simple random weighted strategy with two nodes. When one node can't serve data, strategy should forward the Interests to the same `NameTree` 
 2. call `fib.findLongestPrefixMatch("/")`; since FIB other node. 

 The strategy code is empty, this returns `Fib::s_emptyEntry` 
 3. call `measurements.get` with here: https://github.com/dibenede/nfd-strategies/tree/master/weighted-load-balancer 

 We see NFD crashes while measurement    info is accessed. I am attaching the FIB entry obtained from step2 full trace. 

 Expected: a Measurements entry of ndn:/ is created   
 Actual: crash
