Thanks for your quick response!

To be honest, I only have a very basic understanding of the matter. The
original discussion of the implementation in FreeBSD can found here:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192320
https://reviews.freebsd.org/rS303795

If you feel that this should be solved differently on FreeBSD's end, I will
re-open discussion there. If that doesn't lead anywhere a workaround in GCC
would be great, but since this actually affects all currently released GCCs on
FreeBSD11, I would prefer an OS solution as gcc patches would likely only land
in the most recent GCC-branch(es), right?
