The F-16 works. I have updated to current git (as of the time of this e-mail).
I'll post the backtrace again. It hasn't changed since I last posted, but here it is. My guess is that it's a graphics problem, and something specific to the c172p triggers it. Also, randomly, remember that I know how to use the debugger, so if it helps, I can probe variables, etc. Backtrace from gdb: #0 0x00007ffff5fb6410 in osgText::String::createUTF8EncodedString() const
