 Some of these are **unsound**, which means they can lead
 to Miri failing to detect cases of undefined behavior in a program.
 
-* `-Zmiri-allow-uninit-numbers` disables the check to ensure that number types (integer and float

-* `-Zmiri-allow-ptr-int-transmute` makes Miri more accepting of transmutation between pointers and
