I think the problem is somewhere deep in libc6-2.1.94.  For some 
reason ipv4 addresses are okay, but ipv6 addresses cause seg faults. 
For instance, if (somehow) you got an ipv6 connection to a machine 
with libc6-2.1.94 (say, old ssh connections that were around after 
the upgrade) and you run netstat -at, netstat will core dump on 
hostname lookup of the ipv6 stuff.  netstat -nat will not result in 
a core dump, and you can see the ipv6 stuff.

I don't think more building is going to help here.
