I updated plib, SimGear, and FlightGear before rebuilding. I cleaned everything on Windows because there were some changes to plib headers (MSVC isn't always smart enough to properly handle header changes if they are not in YOUR project). I haven't cleaned the MacOS build because gcc hasn't had such problems.

Just to double check, David made a change to SimGear and to the some of the aircraft config files yesterday. Without the change to simgear, flightgear will crash on startup.If that's not it, then we'll have to take a closer look, although your line numbers don't make sense in your back trace ...

The error was in the same routine, so I am assuming that there is
something uninitialized somewhere. The bad pointer was in slightly
different lines of code, though:
if ( ovState != NULL )
ovState -> force () ; <--- Windows Crashes
else
basicState -> force () ; <--- Mac Crashes
Windows died where it did because ovState contained the Windows
non-zero invalid pointer value (0xcacacaca).
