GNU Make 4.1 has a problem that causes it to be unable to use the desired level of parallelism. Two people have reported that reverting a commit which changes from fork to vfork "fixes" it. (i'm one of them, unfortunately posting as anonymous in the tracker).
Hoewver, if you are also seeing the linux kernel version as relevant to producing the problem, that's quite interesting, and the underlying cause may be different. We reproduced the problem on a range of older kernels, from 3.2 to 3.18. http://savannah.gnu.org/bugs/?44555 Jeff -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
