How can I debug Segmentation fault in C code with inlining function?

Question

How can we debug the segmentation fault in a program which has been compiled without "-g" option?

Answer 1

You can do the following:

1. Very first go through your program and comment out the the line of the code on which you have doubt
     and try to compile and run the program. If it is working fine, then you know that which line is making your
     code to seg fault.

    /* If you are not able to find out using this, try 2nd one */

2. use "gdb",   before using gdb you have to compile your code with -g option in gcc to store the debug information.
       gcc -g your_program.c           // it will give an a.out exutable

       gdb ./a.out
       ...
       ... // you will get something like this
       Reading symbols from ./a.out...done.
      (gdb)  
      <just type start and enter>
       and for every (gdb) now type "n" for next statement.
       untill you get your line where you are getting seg fault.

   for more info regaring gdb see the manual page of gdb.
