I get the same thing, "Bus Error". How did you get all that output, though?, some debugging mode?
strace does it :) a nice tool ltrace could also do some nice output
Look at traceroute.c (main source): At lines 299--300, hou will see struct sockaddr_in whereto; /* Who to try to reach */ struct sockaddr_in wherefrom; /* Who we are */ Later on, in main() at 364, you will see register struct sockaddr_in *from = (struct sockaddr_in*)&wherefrom; register struct sockaddr_in *to = (struct sockaddr_in *)&whereto; Later yet, you will see some calls like this one at 717: setsin(from, al->addr); and finally setsin() at 1340 in its entirety is void setsin(register struct sockaddr_in *sin, register u_int32_t addr) { memset(sin, 0, sizeof(*sin)); #ifdef HAVE_SOCKADDR_SA_LEN sin->sin_len = sizeof(*sin); #endif sin->sin_family = AF_INET; sin->sin_addr.s_addr = addr; /* <<<<<< BUS ERROR HERE >>>>>> */ } The bus error is on the comment; the problem is that the 'struct sockaddr' is not necessarily aligned in such a way that a 'struct sockaddr_in' can overlay it and hope to have the fields nicely laid out for sparc.
There is a patch that corrects this. It won't currently apply nicely. Working on getting it to apply by re-generating the patch.
