That's really strange; I can't imagine how timing could be important.
Perhaps more likely there's some kind of memory allocation/
overwriting issue, and when you start changing trace options you
influence how the allocations and access happens.
It would be good to somehow figure out what's really going on, as
this might indicate a potential bug in any or all implementations; we
just happen to "get lucky" on the other platforms so far, and not
actually trigger it. Or, of course, it could be something specific to
the MikTeX port.
