Comment 3 for bug 1964777

An -O0 build later for debugging...

SimpleSpiceDisplay *ssd is ignored, the value qemu_spice_display_is_running
returns is the global spice_display_is_running of ui/spice-core.c

$6 = (int *) 0x55555650d5b4 <spice_display_is_running>
That is always 0 up to the point this checks it.

A watch on ~/work/qemu/qemu.git/ui/spice-core.c spice_display_is_running did
not see it enabled either.

Cross checks by Athos and Andreas confirmed it is not just a silly setup of
mine - the problem happens the same way for them.
