GDB can't create a breakpoint

I am working on implementing a simple stack overflow, which I am examining with gdb. A problem I keep coming up with is gdb not accepting my breakpoints. My c code is quite simple:

void function(int a, int b, int c) {
   ...//stuff
}

void main() {
  int x;

  x = 0;
  function(1,2,3);
  x = 1;
  printf("%d\n",x);
}

And i'm using gcc -m32 -fno-stack-protector -o example3test example3test.c to complie it.

I have tried just setting a simple breakpoint on the line <+42> just to test if it works.

I'm lost as to why it won't accept this breakpoint. Most of the answers already on here involve not using the * or using wrong notation, from what I can see mine looks right, but I could be wrong.

You have a position independent executable, which is relocated to a different address at runtime.

This will work:

(gdb) start
# GDB stops at main

(gdb) break *&main+42
(gdb) continue
