It is most likely a compiler/setup issue. My guess your machine got out
of memory, and the OOM killer killed cc1. Try adding more memory and/or
swap, it should work.

Some of qemu's code does seem to trigger rather excessive memory
use by gcc; for instance we've had problems with memory usage
building for ARM with gcc of target-sparc/translate.c wanting
gigabytes of RAM with some compiler flags:
https://bugs.launchpad.net/gcc-linaro/+bug/714921

I suspect it's all those large switch statements...

It's on my todo list to report it to GCC, since this memory-hog behavior is a GCC regression.
