gdb - c program seg fault not making sense to me (c beginner) -


this program compiles when run outputs few of first print statements in find() method issues segmentation fault:11 when loop hits.

so tried debugging gdb not figure out problem is. gathered gdb seg fault occurs because of 1 of strstr() methods. also, noticed program shuts-down right before call loop in find method. can tell me why program compiles crashes @ run-time?

here output gdb:

program received signal exc_bad_access, not access memory. reason: kern_invalid_address @ address: 0x0000000000000001 0x00007fff8d6469c4 in strstr () (gdb)

thanks , help. complete beginner practically c, trying learn more.

 char *stuff[] = {  "butthead likes acdc , tv", "beavis likes metallica , tv", "cartman likes eat", "spiderman likes theater , working-out", "silver surfer likes surfing , space", "gunsword likes mustard , exoskeletons" //<---- ,  "meatwad likes tv"  };

you forgot "," because data not enough
