That's quite common; when the stack is corrupt (and possibly in some other 
circumstances on older systems), the function to count the stack frames will 
segmentation fault.
The stack frame unwindiing code therefore wraps things in a signal handler to 
catch attempts to walk off the end of the stack, and recover/continue.
