   simple ASM prog segfault

   Hello,   
      
   I am just starting to learn writing some fun progs in asm.   
      
   I just jotted down some instructions, assembled it and linked it.   
   Running it just segfault.   
      
   The question is: why ? :)   
      
   The program is just this:   
      
   .section .data   
      
   .section .text   
   .globl _start   
   _start:   
      
   movl $1, %eax   
   movl $0, %ebx   
   int $0x80   
      
   As you can see, it just does *nothing*   
      
   Assembled it using: as   
   Linked it with ld   
      
   This is running on a WSL Debian system (should matter I guess)   
      
   Any pointer on what's wrong with this ?   
      
   Thanks.   
      
   N.B: I am just an amateur and I do not plan writing serious things atm, just   
   having fun :)
