> The Clang RandStruct support is implemented similarly to GCC and intended as compile-time hardening to make it harder for attackers to retrieve data from program structures. The support can be enabled via the "-frandomize-layout-seed=" or "-frandomize-layout-seed-file=" options for providing the deterministic random seed for allowing reproducible builds. So if the struct needs to be shared across compile units they have to use the same seed in a specified source file. Seems of limited use given Linux source is freely distributed which would include these seed files.
