| At least for s390 the problem is not buildd resources. s390 has a 31bit | address space, which g++ manages to exhaust compiling this insane source | file. That can't be fixed by rescheduling.
So what do we do?
My suggestion would be to drop the optimisation level to -O1 (and if thatfails -O0) on the problem architectures. Dropping the optimisation is not ideal but it's better than losing the package completely IMO.
