With the release of GCC 14.1 earlier this month[1], they introduced a
few new security related options, most notably -fhardened[2], which
according to the documentation[3], "(e)nable a set of flags for C and
C++ that improve the security of the generated code without affecting
its ABI (...) intended to be used in production builds (...) supported
on GNU/Linux targets."

While I would think its use should cause no side effects, has anyone
built and run sendmail compiled with such flags? If so, any noticeable
difference/errors/warnings/changes to any behavior?
