Bonus points if you can reduce this testcase further, see
https://gcc.gnu.org/wiki/A_guide_to_testcase_reduction
for how to take the preprocessed output and automatically
reduce it to a much smaller file.
And by 'bonus points', I mean 'that's the first thing a
toolchain maintainer would probably do, so handing it
to them on a silver platter would help get their attention'.
