Speaking to Tim on IRC, I'm sort of swayed back to this some uninitialised data scenario. The key question is, is there a configuration, for some people (as in, compiler version, compile options, FG version, SG version, metar settings, aircraft) that will *always* crash? If we have that, then it's easy to test fixes - without that, we'll always be guessing. Incidentally, -O0 often implies that all values are initialised to zero, which could by why it fixes the problem. Valgrind should catch such an issue, if anyone is able to actually fly FG while running under VG - on Mac the performance is too slow to take off. It would still be interesting to do the CVS binary search if someone has time to spare, just to establish an upper bound on when the problem might have been introduced.
