Bug#1004017: qemu-system-x86_64: assertion failure in parsing code of SLIC ACPI table

[Wouter Verhelst]

Package: qemu-system-x86
Version: 1:6.2+dfsg-1
Severity: important
Justification: qemu always crashes at startup in one (fairly common) use case
Forwarded: https://gitlab.com/qemu-project/qemu/-/issues/786

When called with the necessary parameters to loop through the Windows
license key that is embedded in my laptop (through libvirt), qemu fails
with an assertion:

internal error: qemu unexpectedly closed the monitor: qxl_send_events: spice-server bug: guest stopped, ignoring
**
ERROR:../../hw/acpi/aml-build.c:61:build_append_padded_str: assertion failed: (len <= maxlen)

Resulting in a failure to start the Windows VM.
