Details:
mtr 0.80 from the 'mtr-tiny' Debian package sometimes fails with the following
message:
--
# mtr www.sixxs.net
mtr: ../sysdeps/posix/getaddrinfo.c:2297: getaddrinfo: Assertion `((((__const
uint32_t *) (sin6->sin6_addr.__in6_u.__u6_addr32))[0] == 0) && (((__const
uint32_t *) (sin6->sin6_addr.__in6_u.__u6_addr32))[1] == 0) && (((__const
uint32_t *) (sin6->sin6_addr.__in6_u.__u6_addr32))[2] == (__extension__ ({
register unsigned int __v, __x = (0xffff); if (__builtin_constant_p (__x)) __v
= ((((__x) & 0xff000000) >> 24) | (((__x) & 0x00ff0000) >> 8) | (((__x) &
0x0000ff00) << 8) | (((__x) & 0x000000ff) << 24)); else __asm__ ("bswap %0" :

Aborted

The system has both IPv6 and IPv4.
Reproducible only sometimes, it may require multiple attempts on different
dual-stack hostnames to get this assertion to trigger.
