Re: segmentation faults

Hi Richard,

I ran into the same type of thing upgrading from
2.4.19 to 2.4.24 (or any really) it turned out to be
to be related to libpthreads that are optimized for
i686.  I've moved the /lib/i686 and it "cured" my
problems.  My problems seemed to be a little more
sporadic that what you're experiencing but it's worth
a look.
