By the way, just testing my workaround for this (setting a breakpoint and
continuing rather than single step) and it appears to effect both pushfq
and popfq. Even after I fixed the pushfq case the problem still occurred
because it set the TF on the popfq despite the fact the stack value didn't
contain TF.
Cheers,
David
