I've been observer quite frequent segfaults in the most recent version of
FlightGear. I've started running under gdb and so far the trend seems to be
that the crash is inside the pui code and as a result of clicking "ok" or
"cancel" on a dialog box. Here's an example backtrace (the build is without
-g though). Anyone else seeing this? I'm using plib-1.8.5 and OSG-2.9.5.
Boost is 1.37.
