adapted for trunk and older GCCs and Clang, removed warnings
Here's the a little bit hand-simplified version (I mostly removed redundant
attributes and header lines) that works in earlier GCCs, LLVM, latest trunk.
LLVM's sanitizers don't find a problem.
It fails with O2 or O3 since 7.1. I can't bisect because I only have aarch64 vm
on mac and they haven't responded to my cfarm account request yet, so someone
else has to do the bisection since the trunk of earlier than 2018 can't be
built on aarch64.
If you open a text editor and replace the single occurence of
__attribute__((used)) with nothing, which is the single use of the attribute
"used" in my cleaned up version, the segmentation fault is gone.
