Title:
  bios_linker_loader_add_checksum: Assertion `start_offset <
  file->blob->len' failed

Status in QEMU:
  Fix Committed

Bug description:
  Trying boot/start a Windows 10 VM.  Worked until recently when this
  error started showing up.

  I have the following installed on Fedora 33:
  qemu-kvm-5.1.0-9.fc33.x86_64

  This is the error:

  Error starting domain: internal error: process exited while connecting
  to monitor: qemu-system-x86_64:
  /builddir/build/BUILD/qemu-5.1.0/hw/acpi/bios-linker-loader.c:239:
  bios_linker_loader_add_checksum: Assertion `start_offset <
  file->blob->len' failed.

  Traceback (most recent call last):

  I see this were referenced in a patch from some time ago and
  supposedly fixed.  Here is the patch info I was able to find:
