A Question On GDB?

Gentle People:

    I normally use GDB to find Segmentation Fault bugs such as
an uninitialized pointer. Usually I just use the "r" command and
the program runs until it crashes with GDB displaying the source
code file name and line number!

    But in the case shown below GDB dose NOT give me this
this useful information?

     Now the question: How can I find the crash point in the code?

Thanks for the help
