--- Comment #3 from Steffen Hau <steffen at hauihau dot de> ---
I don't know wether this is a GCC issue, but I have recompiled all my packages
on Gentoo with GCC 5.1.0 and LD Gold from binutils 2.25 and ran into the same
error for Qemu 2.3.0:

The same happens with LD BFD. Only workaround is to disable LTO. GCC 4.9.2
doesn't show this error and compiles the code. I was able to break down the
Object List to three files which reproduce the error reliably. I compiled the
files with the "--save-temps" switch, but I'm not able, to reproduce the error
with the resulting .i files because of other compiler errors like "'abc' does
not name a type" or "error: 'xyz' was not declared in this scope".
I'll attach the preprocessed sources as well as the commandline options I've
used to compile and link. Please let me know if I need to provide further
information.
gcc -v
Using built-in specs.
