Hi,

as discussed in the PR, this patch adds a new reduced testcase which
doesn't rely on c++17 features, this is a prereq to the backport of
the fix into GCC 6 branch which is impacted by this issue.

Validated on x86, ARM and AArch64 targets.

Ok for trunk ? and maybe on gcc-7-branch ?

Thanks,
Yvan
