Bug #2493

Updated by Junxiao Shi almost 10 years ago

NFD commit:0d6d036e4f0a504c856453788808794c122adfaf commit:a788e25e70f5a210c0623942986155f283e55261 on Ubuntu 12.04 

 Snippet to reproduce: 

 ``` 
 // g++ --std=c++0x x.cpp `pkg-config --cflags --libs libndn-cxx` 

 #include <ndn-cxx/management/nfd-face-monitor.hpp> 

 int main() 
 { 
   ndn::Face face; 

   ndn::nfd::FaceMonitor facemon(face); 
   facemon.onNotification.connect(std::bind([]{})); 
   facemon.start(); 

   face.processEvents(); 
   return 0; 
 } 
 ``` 

 Steps to reproduce: 

 1. console A: `sudo valgrind nfd`, wait until initialization completes 
 2. console B: `./a.out` (the binary compiled from snippet above) `nrd` 
 3. wait 5~20 seconds 
 4. console B: press CTRL+C 

 Actual: valgrind complains 

 ```

 ``` 

 Note: This error occurs only for the first time when `a.out` is terminated. If `a.out` is started again and then terminated, the error won't appear again. 

 Expected: no such error
