Re: backtrace shows ?? instead of function names in gdb
That looks like an indirect call through a NULL function pointer. Never
a valid function, thus it never has a name.

"And now for something completely different."
Thanks for the prompt response.
I will investigate this matter by doing code review.
Whether this is the only reason that such a peculiar backtrace is
produced ? If you refer to the link given in my original post, the
answer posted states several reasons.
