breaking on main in the trivial program:
int main() {
}
breaks at a location without source code

(gdb) break main
Breakpoint 1 at 0x4004d0
(gdb) r
Starting program: /home/blaikie/Development/scratch/a.out 

Breakpoint 1, 0x00000000004004d0 in main ()

rather than GCC which:
(gdb) break main
Breakpoint 1 at 0x4004d0: file main.c, line 2.
(gdb) r
Starting program: /home/blaikie/Development/scratch/a.out 

Breakpoint 1, main () at main.c:2
2       }
