Public bug reported:
getifaddrs is a function to fetch a list of network interfaces. The
version provided by eglibc in lucid and earlier has a know bug where it
will call abort() when interfaces are added/removed during the
getifaddrs operation. This is somewhat problematic because it will cause
daemons to exit, and can be triggerd by for example stopping / starting
virtual machines. This problem has been seen under real-world conditions
and will lead to the following gdb trace:
#0 0x00007fd2727604b5 in *__GI_raise (sig=<value optimized out>)
