It also affected eMacs compilation and the fix is in the trunk now.

Wow 11 years for such a banal minimal code trigger. I really don’t quiet understand how we can have the scale of infrastructure in operation when this kind of infrastructure software bugs exist. This is not just gcc. All the working castle of cards is an achievement by itself and also a reminder that good enough is all that is needed.

I also highly doubt you could get a 1 in 1000 developers to successfully debug this issue were it happening in the wild, and much smaller to actually fix it.
