Sorry for the noise, I didn't know how it worked here.

Anyway this duplicates Bug 85180.

Another test case demonstration the problem

This additional test case comes from ffmpeg 3.2. This file builds fine with
-Os, but makes the compiler use 100% CPU time indefinitely with -O1, -O2 or
-O3.

This bug still exists with gcc 6.1.0, in the same condition (same test case,
same architecture, same optimization levels that work / don't work).
