Ah, right.  I think the patch for ckpasswd is fine.

Well.  It turns out that gdb-5.x doesn't behave very well on Sparc
Linux.  I'm playing around with gdb-4.18 again now and I'm getting
somewhere if I attach to the running process before it dies.  Examining
a core file is still a dead loss though...

There have been two separate causes of segfaults.  One stopped somewhere
in ov3.c when I had tradindexed configured.  Unfortunately, I've lost
the backtrace and subsequently switched to ovdb to see if that solved
the problem.  It did.  I'll switch back sometime today and test it
again.

The other one is in the Perl filter:

Switching off the Perl filter (adding 'innflags: -N' to inn.conf) solves
the problem.  The filter_innd.pl is still the default from the inn
distribution.  Perl libraries are 5.6.1.  I'll play around with it
again this afternoon and see what else I can come up with...
