C Code to get a shell is not working on my Ubuntu 20.04

I am trying to run this code to get a shell but I am getting a segmentation fault even with ASLR disabled. I am running this code on my AMD Ryzen 3 computer with Ubuntu 20.04 64bit version.

I am compiling with the following command:

gcc -O0 -fno-stack-protector -z execstack getshell.c -o getshell

File getshell.c is as following:

#include <stdio.h>

unsigned char shellcode[] = \
"\x48\x31\xf6\x56\x48\xbf\x2f\x62\x69\x6e\x2f\x2f\x73\x68\x57\x54\x5f\x6a\x3b\x58\x99\x0f\x05";
int main()
{
    int (*ret)() = (int(*)())shellcode;
    ret();
}

Kindly guide me what am I doing wrong here.

>Solution :

unsigned char __attribute__((section(".text#"))) shellcode[]

works for me (mind the #)

# is a trick – it comments part of the emitted assembly code by gcc.
