Emulated/Virtualized environment

  • Operating system: Windows 10/11
  • OS/kernel version:
  • Architecture: ARM64

Description of problem

After booting Windows 10 or 11 (ARM) QEMU suddenly quits with:

ERROR:tcg/optimize.c:580:do_constant_folding_2: code should not be reached

It seems like it is missing an OPCODE in that function?

Steps to reproduce

  1. Boot Windows
  2. QEMU quits
