Yes, that's right. There was provision for dynamic areas to be mapped in/out
with their parent application (see flag bit 11 for OS_DynamicArea 0) but not
yet implemented - so we can rule-out dynamic area contents if it really is a
LTS bug.

I suspect you're right. I also think there must be some common factor
between the systems of all the people who do see the fault. It'd be handy to
find that.
