Any other info needed?

Seems strange that if nothing has changed between 10B-5 and 10B-6/7, that
all of a sudden there would be segmentation faults. I can believe some
pthread dependency/feature change in HIPE was added/changed that finally
broke the linux threads in favour of POSIX threads (note, I am using 10B-7
on an OpenBSD 3.6 system with no problems).

If somebody has a newer Gentoo system (2.6 kernel please) where 10B-6/7 is
working, I would love to hear from you to see if this is an issues with a
slightly older kernel/libraries.

Regards!
