Reduced preprocessed source that induces the error message
When trying to build a cross-compiler for cris with libgcc, I get the following
error and several others like it (make -j is in operation) during the compiler
build:

The bug is not reproducible, so it is likely a hardware or OS problem.
I'm also very intrigued by that last line - I can reproduce it quite easily.
Anyway, I've added a reduced libgcc2.i that causes the error to occur. I don't
think it'll help because you need the intermediate-stage compiler binaries
also.
System gcc being used to build the cross-compiler:
Using built-in specs.
