I'm not sure which address/opcode this occurs because that isn't logged.

But I suspect it's opcode 0x99 (CDW) or its prefixed variant 0x66 0x99 (CDQ).
That exists in a 16 and a 32 bits variant but takes no parameters at all.

This is being fixed as well, was caused by the changes to adapt the generator to the 32bits changes done on spice86.
