Tried to reproduce without success.
I enabled sanitizer in spice-server and run the command with stock (packaged) Qemu,
no issues.
Normal tests have no issues too.
>From timer_remove (spice-core.c) code looks like a corruption of "timer" pointer,
if I read correctly faulty address is 0x00009fff8000 which does not tell me much at
the moment.
I don't understand why GObject is emitting a signal here but I cannot see any
issue, maximum the signal is sent before reds pointer is set but there's a check
for it in red_char_device_on_sin_changed.
Could be that write_to_dev_timer is not initialized to NULL by GObject? Everything
should be initialized by 0 by GObject. Can you try to manually initialize to NULL
in red_char_device_init?
I see you are using your own version of Qemu. Can you try the stock one?
Which commit of Qemu are you trying?
