On my box (generic unpatched Solaris 10 on amd64), segfault strongly depends on
stack layout:
atari:venglin:~> traceroute -s 1.1.1.1. 127.0.0.1
traceroute: 144.144.91.194 is an invalid IPv4 source address
atari:venglin:~> setenv DUPA `perl -e 'print "A"x500'`
atari:venglin:~> traceroute -s 1.1.1.1. 127.0.0.1
traceroute: 4.0.0.0 is an invalid IPv4 source address
Segmentation fault
It might be also specific to x86 architecture.
