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. Linus
