400 lines is too much. In gdb just run the program (not step) and when 
it seg. faults do a backtrace (bt). You can print the value of a 
variable with print varname. You can also print the value of an 
expression with print, so to print a dereferenced pointer do print 
*ptrname. To move up or down the stack frame use the commands up and 
down. Please post text rather than images.

I haven't seen this before.
