ARDroneLib Assertion failure when exiting Ardrone_Autonomy. #8

I've built ARDroneLib & Ardrone_Autonomy with debug symbols and everything seems to work ok. However, when I exit (Ctrl-C) from Ardrone_Autonomy, I get:

ardrone_driver: ..//VP_Os/vp_os_malloc.c:53: vp_os_free: Assertion `ptr' failed.

during the shutdown phase.

Short of enumerating all the calls to vp_os_free, I'm not sure where the error's coming from.

Cheers,
