segfault in getifaddrs() in glibc 2.3.2-27.9

[Jeff Moore]

sudo seems to segfault when I have more than 41 interfaces (my case 
uses virtual interfaces)...This only seems to happen under 
glibc-2.3.2-27.9, it works under glibc-2.3.2-11.9
Relevant part:
Program received signal SIGSEGV, Segmentation fault.
0x40155ecf in getifaddrs () from /lib/i686/libc.so.6

Thank you.
