Macos get pointer being realloc'd was not allocated error in gas assembly

Question

I am writing a simple compiler for gas assembly on macos which generated this assembly:

    .section __TEXT, __text
    .globl _print
_print:
    pushq %rbp
    movq %rsp, %rbp
    movb $0, %al
    call _printf
    xorl %eax, %eax
    popq %rbp
    retq
str0:
    .asciz ""
    .globl _main
_main:
    pushq %rbp
    movq %rsp, %rbp
    leaq str0(%rip), %rax
    movq %rax, 0(%rbp)
    movq ___stdinp@GOTPCREL(%rip), %rax
    movq $0, 1(%rbp)
    movq (%rax), %rdx
    leaq 2(%rbp), %rdi
    leaq 1(%rbp), %rsi
    callq _getline
    movq 0(%rbp), %rsi
    movq 0(%rbp), %rdi
    callq _print
    xorl %eax, %eax
    popq %rbp
    retq
.subsections_via_symbols

And run it using:

gcc -c main.s -o main.o gcc main.o -o main ./main

But whenever I use ./main I get: main(13366,0x1132f8e00) malloc: *** error for object 0x5f00000000000000: pointer being realloc'd was not allocated main(13366,0x1132f8e00) malloc: *** set a breakpoint in malloc_error_break to debug

I don't know what I could do to fix this and have no idea what is going wrong so any help would be appreciated!
