Some UML person should really take a look. It might be a compiler bug that 
is triggered by -fno-unit-at-a-time, but considering that x86 is the most 
tested architecture by far and apparently does *not* hit that problem, it 
sounds more likely that it's UML-related and the compiler just triggers a 
bug in UML.

Anybody?

Yes, I'll revert that commit, but just reverting it without somebody 
trying to figure out what is wrong with UML isn't good.
