I can't tell you why either, I'm sorry. I can just point to the
documentation, which does specify that "On some machines it may be
impossible to determine the return address of any function other than
the current one". If somebody knows what this depends on, feel free to
interject.
https://gcc.gnu.org/onlinedocs/gcc/Return-Address.html

On my NXP LS1028A (also arm64) plus clang-16 compiler, __builtin_return_address()
does work with multiple nesting levels.

I guess. Sounds good.
