FWIW, I;m seeing an occasional segfault. Today, I managed to trap it using
gdb. below is the complete stack trace. IIRC, 2D texture loading has been
giving occasional problems. This particular error occurred in my new traffic
manager version of Flightgear. It doesn't seem to make much of a difference, I
guess.
