I'm getting the same problem. I keyworded 5.1.0 as a test, and it did the same 
thing.

Perhaps my search skills are lacking, but I cant see anything else about this 
for GCC v5 (yet).

Was planning to poke at it for a few more days before putting in a bug report.

I've included the first part of 'emerge --info' for my system below. Is yours 
similar?
