I'm trying to use a function in assembly in a C project, the function is supposed to call a libc function let's say printf() but I keep getting a segmentation fault.

In the .c file I have the declaration of the function let's say

int do_shit_in_asm()

In the .asm file I have

.extern printf
.section .data
         printtext:
              .ascii "test"
.section .text
.global do_shit_in_asm
.type do_shit_in_asm, @function

do_shit_in_asm:
    pushl %ebp
    movl %esp, %ebp
    push printtext
    call printf
    movl %ebp, %esp
    pop %ebp
ret

Any pointers would be appreciated.

as func.asm -o func.o gcc prog.c func.o -o prog
