Comment 7 for bug 1222377

This bug is still present, up to and including Ubuntu 14.04 Trusty. large_interface_counters.patch enlarges the buffer at common/discover.c:420 in begin_iface_scan(), but not the buffer at common/discover.c:493 in next_iface4(), which is where the error occurs (see comment #3).

The following buffers should be enlarged from 256 to 512 bytes:
common/discover.c:493:next_iface4()
common/discover.c:617:next_iface6()

I still haven't heard anything from ISC other than they were going to consider this, so it looks like Debian patching it is the correct solution.
