On Ubuntu 16.04 (Boost 1.58) tracked the seg fault to commit: 756cba6 
Sun Jan 31 00:32:25 2016 +0100

"Added support for increased thread stack sizes when boost 1.50 or later 
is used."

Was about to try bumping up the requested thread stack sizes some.

Wondering some about the change on linux where I think the commit  above 
means we moved from whatever was being set with the 'official' boost 
package to something hard coded in povray. At least if I'm following the 
change and understanding the windows vs linux boost set up correctly?
