I'm sure that recompiling FlightGear with the vanilla profile will solve this, but I might as well report it.

Indeed, the vanilla profile hides the bug.
A quick glance at the code and it does a lot of data declaration inside local blocks so I suspect this is the same compiler issue we see elsewhere.
GCC 4.3.4 is stable on hardened. GCC 3.4.x is frozen/not being worked on. Closing as WONTFIX.
