SIGBUS? So an alignment fault rather than a crash, it seems, and yes it's likely
due to the extended length (the 130 ASNs themselves aren't a problem, other than
they need extended length in the attribute header - the extra byte throws off
the alignment. I'm not sure where or how the old code does unaligned reads
though - my vague memory is that it did byte reads via a char * always..). 

(Also weird that Linux didn't fixup - I thought Linux always did on all
platforms, where possible, unlike most other *NIXes. Linux did trap and fixup on
AXP anyway).

Can you test 0.99? Compile it and cd to to the 'tests' directory, run make there
and aspathtest. If it doesn't fault, and reports no errors, I would expect 0.99
bgpd should be immune to the bug below.

Thanks, Paul.

We'll have to leave it for a few days because as you can imagine our customers
still aren't too happy about the downtime we had. Even out of hours testing will
need left for a few days.

If any one can simulate a 100 plus AS path length test in the meantime then
please do !

I can't believe we are the only ISP running Gentoo SPARC64 globally !
