"BSD compiler toolchain" is just a GNU toolchain that is a decade plus old.
It will be probably twenty years before someone programming on BSD will have some code wrongly deleted as unreachable because it comes after realloc(ptr, 0).
They are immune from the damage.
For instance, OpenBSD 6.8 was released in 2020. On that release, gcc reports as 4.2.1, released in 2007.
