Title:
  tcg.c:3329: tcg fatal error

Status in QEMU:
  Confirmed

Bug description:
  I am currently building my own kernel with bootloader and qemu crashed
  after I have set an IDT in protected mode and then create a invalid
  opcode exception with the opcode 0xff.

  My code is here: https://github.com/Luis-
  
Hebendanz/svm_kernel/blob/qemu_crash/svm_kernel/external/bootloader/src/main.rs#L80

  Build instructions are here: https://github.com/Luis-
  Hebendanz/svm_kernel/tree/qemu_crash

  A precompiled binary is here: https://cloud.gchq.icu/s/LcjoDWRW2CbxJ5i

  I executed the following command: qemu-system-x86_64 -smp cores=4
  -cdrom target/x86_64-os/debug/bootimage-svm_kernel.iso -serial stdio
  -display none -m 4G

  I am running QEMU emulator version 5.1.0
