The cancellation tests have always been somewhat problematic. Helge wrote a couple of weeks
ago and he thought there was an unwind issue. We will investigate as soon as possible. At the
moment, we are trying to debug a kernel/gcc bug that causes a bootstrap failure. I would guess
the new optimizations in gcc 5 are causing problems.
