Talking about this particular PR, I can't even reproduce it w/ all the targets
I have: it works well w/o ICE for powerpc-e300c3-linux-gnu, for example.

As of PR70623, for me it started triggering ICE somewhere between
6.0.0-alpha20160110 and 6.0.0-alpha20160403 for both
powerpc-e500v2-linus-gnuspe and x86_64-pc-linux-gnu. I failed to reproduce it
w/ 4.9.3 and 5.3.0 configured for all four targets mentioned by me here. Given
your comment, I'll certainly try it in the days ahead w/ the flavor of
arm-none-eabi that I have.

In case I've got you wrong, what configure options do you want me to make
specific?
