Please report a bug again linaro toolchain with the test case and cmd line options at https://bugs.launchpad.net/gcc-linaro
Ok, filed as https://bugs.launchpad.net/gcc-linaro/+bug/1268893
If this blocks your work, please remove "-g' option to workaround it.
Thanks for the hint!

What's your option to compile the file?

Can you attach the preprocessed C file? Add option --save-temps to compile neon4 source file. Then you will get a temp file neon4.i

I believe the kernel build system can get you the pre-processed source with, e.g.:
# make lib/raid6/neon4.i
The kernel does support that, which makes this a lot easier. Neon4.i is attached. I forgot to mention, this is with gcc 4.8:
