No, it does not report anything.

Hatari just freezes:
------------------------
VDI 0x65/0x00 (v_clsvwk)
WARNING: xconout stack args not found by skipping return addresses, 
trying short skipping.
WARNING: xconout args not found from stack.
<freeze>
------------------------

When I enabled cpu_symbols tracing for EmuTOS, in addition to tracing 
all OS calls, I saw something fairly weird in the log (attached).

It seems like EmuTOS would proceed after VDI close to panic, halt and 
reboot, and then continue booting, without *anything* being visible on 
Hatari screen, or xconout interception working.

Maybe the reason for CPU core freeze is some weird MMU setup done by 
EmuTOS v1.1.1 that had corrupted its state?
