Description Timothy Miller 2015-05-16 20:10:15 UTC 
I'm trying to build gentoo-sources-4.0.3, but it doesn't compile.  When it dies, I see a failure to compile some module.  But when I look in the log, I don't see any mention of that at all.  Instead, I see an internal compiler error.  What?  

So the problems are:
- The compiler is crashing, which means nobody has tried compiling this configuration of 4.0.3 with gcc 4.8.4.
- A build failure is occurring that is not being recorded in the log file.
- The kernel contains code that doesn't compile.


Here's what prints to the screen:

This doesn't appear anywhere in the log.  Instead I see this:

Note that the compiler crash happens every time, so this isn't some kind of intermittent hardware problem.
