I just built math/blas 3 times on a Linux machine with 16 cores and
MAKE_JOBS=8. Scratch space is a local SSD. No issue … 

29.08user 3.07system 0:12.33elapsed 260%CPU (0avgtext+0avgdata 28676maxresident)k

trying math/lapack

… indeed, I got a failure right now. Rather quickly:

717inputs+182203outputs (0major+422689minor)pagefaults 0swaps

Another run. Success.

Third time. Success. Fourth time. Failed.

So there is an issue. I do think it's the same every time:

Is your error different?

Alrighty then,
