On most OS platforms fprintf() et.al. are considered to be signal unsafe. I've noticed the signal handlers in tcpdump call fprintf(). The patch below defers call to fprintf() triggered by signal to pcap_loop callback. Submitted to upstream: the-tcpdump-group#638 (fixes broken build on windows) (s/ifdef/ifndef in my earlier change)
