--- Comment #4 from Arseny Solokha ---
int mw;
int
j3 (int cn)
{
const int l7 = 0;
int wz;
for (wz = l7; wz < l7 + 3; ++wz)
while (mw != 0)
{
cn ^= -(wz == l7);
++mw;
}
return cn;
}
actually leads to ICE w/ -O2 (-O3, -Ofast) -ftree-vectorize all the way from
gcc-8.0.0-alpha20170507 snapshot down to 4.9:

We also haven't seen it in Debian since last May, see: > https://buildd.debian.org/status/logs.php?pkg=stress-ng=powerpcspe stress-ng has been building fine ever since.
