Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009

I have added c++ support to the linux kernel and compiled it successfully. Tried booting the kernel using the command qemu-system-x86_64 -nographic -kernel arch/x86/boot/bzImage -initrd /boot/initrd.img-4.14.41+ -m 512M -append console=ttyS0 but the following erorr occurs

[    0.432000] Fixing recursive fault but reboot is needed!

What might be the cause of the error? There are two different call traces here along with the offsets.So, I tried gdb on object files that are calling these functions. But, gdb says No symbol table is loaded. Use the "file" command. If this is not the right way, what are other alternatives for debugging?
