--- Comment #3 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- (In reply to Arseny Solokha from comment #2) > I can reproduce it w/ gcc 5.4.0, but cannot w/ 7.0.0-alpha20170205 snapshot. We also haven't seen it in Debian since last May, see: > https://buildd.debian.org/status/logs.php?pkg=stress-ng&arch=powerpcspe stress-ng has been building fine ever since.
