Bug #4585
Updated by Davide Pesavento about 6 years ago
The newest version of ndn-cxx produces a bus error or a segfault when the producer example is executed. Here is the output when I ran the example through gdb and got a bus error: ``` (gdb) `(gdb) run Starting program: /home/pi/ndn-cxx/examples/a.out [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/arm-linux-gnueabihf/libthread_db.so.1".
