Doc Type: Enhancement
Doc Text:
.GCC 12 and later supports `_FORTIFY_SOURCE` level 3 With this enhancement, users can build applications with `-D_FORTIFY_SOURCE=3` in the compiler command line when building with GCC version 12 or later. `_FORTIFY_SOURCE` level 3 improves coverage of source code fortification, thus improving security for applications built with `-D_FORTIFY_SOURCE=3` in the compiler command line. This is supported in GCC versions 12 and later and all Clang in RHEL 9 with the `__builtin_dynamic_object_size` builtin.
