Hello!

GNU Make seems to randomly crash on an Raspberry Pi 2 with

   INTERNAL: Exiting with 2 jobserver tokens available; should be 5!

or similar when emerging Gentoo Linux packages using multiple jobs (e.g.
-j5). The kernel log then has lines like

  Segmentation fault occurred at    (nil) in /usr/bin/gmake[make:23312]
uid/euid:250/250 gid/egid:250/250, parent /bin/bash[sh:23311]
uid/euid:250/250 gid/egid:250/250

Is this some known GNU Make bug on ARM?
