This is very similar to attempt 1, but interception is guarded. Since `free_sized` and `free_aligned_sized` are not widely available yet, platforms that cannot handle undefined weak symbols (i.e. macOS) gracefully are excluded. They can easily be supported once they are by updating the definition of `SANITIZER_INTERCEPT_FREE_SIZED` and `SANITIZER_INTERCEPT_FREE_ALIGNED_SIZED`.
