Can you come with a bit pointers or numbers about 'expensive' ?

It is not a bug in the toolchain. It is how the processor specific ABI

A crash is expected to happen because the psABI requires it.
The psABI is broken because it permits a symbol visibility type
(protected) that executables cannot use. But it is how the ABI is.
