I can't reproduce a crash on RHL62 + 2.2.17-14 + telnet to ::1 and.
OpenSSH 2.5.1p2.  2.3.0p1 also tested fine.  I didn't use '--without-4in6'
though, but that shouldn't be significant.

Would this work if you downgraded the kernel a bit (e.g. 2.2.16/17), or
tried the latest -acXX patch?

Unfortunately, no.  Linux IPv6 code has been in a rather static state for
the last 3 years or so.  USAGI kernels (www.linux-ipv6.org) have actually
developed a bit.

Still, IMO this looks more like a very specific problem -- I'm rather sure
2.2.x kernels are fine overall.

Where does the strace stop?
