I definitely need to see the source code for openNetworkDevice().  Presumably its first argument is a reference to a 
pcap_t *, but, if it returns a value, main() doesn't appear to check the value, so, if it fails to open any of the 
devices in the list for capturing, and thus has no pcap_t * value to set handle to, handle might not have a valid 
value, and thus pcap_compile() might crash.  (Perhaps it throws an exception if it fails to open any device.)

An invalid value for handle could cause it to crash.-
