There would have been reports (I maintain the package for Gentoo,
where users build the package on their system)...and there were none.
We use FORTIFY_SOURCE for some time now.

It is included in the trunk version and used by many distributions
nowadays, especially for the server/hardened systems.

Would be nice.
