Hello Dave,
I didn't look deeper into your backtrace. And I even think there're
people who know the code better.
But may I give you some hint? Recompile the source code with
CFLAGS=-ggdb -O0" or CFLAGS=-g -O0". In the backtrace are many values
optimized out. In general a bad situation to start debugging. :-)
But I'm not sure if this helps in your special situation here...
