"Address boundary error" with struct

[lilydjwg]

I am using gcc 4.3.3 on Ubuntu 9.04. The following code:

#include<stdio.h>
struct TEST {
  int test;
};
int main(){
  struct TEST *test;
  test->test = 12;
  printf("%d\n\n", test->test);
}

compiled good, but when I run it, I get the following message:

Job 1, './a' terminated by signal SIGSEGV (Address boundary error)

Can anyone tell me what is wrong with my program? Thanks!

You haven't allocated an object, just a pointer. You need something like:

struct TEST *text = malloc( sizeof(struct TEST) );

and when you're done with it:

free( text );

Oh I see. Thank you very much.
