It’s not a warning, it’s a compile time error and I am not even using -Wall -Werror

I also believe there are platforms where a function pointer and a data pointer are not the same but idk about such esoteric platforms first hand (seems Itanium had that: https://stackoverflow.com/questions/36645660/why-cant-i-cast...)

Though my point was only that this code will not compile as is with whatever clang Apple ships*

I am not really sure how to get it to compile tbqh

Some further research ( https://www.kdab.com/how-to-cast-a-function-pointer-to-a-voi...) suggest it should be done like so:

> auto fptr = &f; void a = reinterpret_cast<void &>(fptr);

edit: I tried with GCC 15 and that compiled successfully
