for some reason I'm having a problem with gdb not hitting my breakpoint set for strcpy(). I have a feeling it has to do with the book being a little bit outdated then the current software I'm using. Any info as to what I'm lacking would be grateful.

 

 

[sysadmin@milkyway booksrc]$ gdb -q char_array2

Reading symbols from /home/sysadmin/code/c/booksrc/char_array2...done.

5               char str_a[20];

7               strcpy(str_a, "Hello world!\n");

8               printf(str_a);

9       }

(gdb) break 6

Break 2 is being skipped. Maybe strcpy isn't being resolved properly. I'm not sure how to fix it.
