preprocessed source file to trigger the segfault

gcc encounters an internal compiler error when compiling our software.
I have preprocessed the affected source file and attached to this bug report.

The command line to trigger the problem is:
c++ -O3 -march=native -c ~/tmp/gcccrash.cxx -o ~/tmp/gcccrash.cxx.o

I am running gentoo linux 64 bit, gcc 7.3.0, glibc 2.26, kernel 2.15.
CPU model is Intel(R) Core(TM) i7-6700K.
The problem appears only when the -O3 and the -march=native options are
present.
