I couldn't reproduce the hang a 2nd time, but in case it'd occur to someone else, I'm reporting the problem here. The build appears to be hung, peeking a single CPU core with no output.

The build of fftw had been ongoing for about 500 CPU minutes. It may be related to the tests using more than one thread (some deadlock perhaps). Maxim
