I think this *might* be a change they made in Intel 9.0, which is why
you're not seeing a problem.  I had an extensive discussion about this
with Intel's support people because it *was* a real problem.  Ralf, do
you remember this issue?  Maybe it has to do with rtti or exceptions
not working across .so boundaries?
