Yeah, that's a sad story, expecially as Yocto is targeting a fix only
for the 1.8M3 milestone (see [1])

This is my understanding, too.

5.6 includes basically the same compiler as 5.5.x; especially the
aforementioned bug is still unfixed.

We did not come to a final decision yet how to handle this.  It wuld
be possible to switch to GCC 4.8.4 for some ELDK v5.6.1 release or
such, but I hesitate as I'd much rather have a community accepted and
tested fix included.

Eventually we might even skip v5.7 and rather focus efforts on a quick
v5.8 which then would (hopefully) a reliable version of GCC again.
