Interesting...
The 10.04 LTS in our lab does not dump core for inet:getifaddrs().
What does this produce for you (mine below, obscured):
1> inet:getiflist().
{ok,["lo","eth0"]}
2> [{If,element(2,inet:ifget(If, [flags,hwaddr,addr,netmask,broadaddr]))}||If<-element(2,inet:getiflist())].
[{"lo",
  [{flags,[up,loopback,running]},
   {hwaddr,[0,0,0,0,0,0]},
   {addr,{127,0,0,1}},
   {netmask,{255,0,0,0}},
   {broadaddr,{0,0,0,0}}]},
 {"eth0",
  [{flags,[up,broadcast,running,multicast]},
   {hwaddr,[11,11,11,11,11,11]},
   {addr,{111,111,111,111}},
   {netmask,{255,255,255,0}},
   {broadaddr,{111,111,111,255}}]}]

And this (mine below, obscured):
$ ifconfig -a
