FWIW: i am seeing some SIGSEGVs with my self-built (via the dnc script) OSG 3.6.5... not sure, yet, what the problem is... i will likely rebuild OSG in full debug more to try to track down more of what is going on... this may be something to do with changes in FG/SG, though...
FWIW2: i have --prop:/sim/sim/nasal-gc-threaded=false...
FWIW3: i am using the DDS cache without compression (because there is no nvtt for my card or OS)...
just for whatever:

"You get more air close to the ground," said Angalo. "I read that in a book. You get lots of air low down, and not much when you go up."
"Why not?" said Gurder.
"Dunno. It's frightened of heights, I guess."
