Since there is a new release coming, I decided to bring the Mac version back up to date (I've been busy otherwise). When I exit FlightGear, I get the following errors (and crash).


*** malloc[8626]: Deallocation of a pointer not malloced: 0x18bef000; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug
*** malloc[8626]: Deallocation of a pointer not malloced: 0x18d8d000; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug
*** malloc[8626]: Deallocation of a pointer not malloced: 0x141794c0; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug


Using gdb gives me the following stack dump.  Any ideas?

Program received signal EXC_BAD_ACCESS, Could not access memory.
