Only the return value of `CALLOC` is converted to `MemorySegment` in an equivalent way, I believe passing a `MemorySegment` to a downcall involves acquiring the corresponding segment? As a result, `FREE` is made to accept the raw address, and `CALLOC` is changed in the same manner for consistency. ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/22610#discussion_r1929440246
