Rust nightly recently [started] issuing the following warning when
compiling coreutils:
[started]: https://github.com/rust-lang/rust/pull/109944
```
warning: getting the inner pointer of a temporary `CString`
--> src/uucore/src/lib/features/entries.rs:324:67
|
324 | let data = $fnam(CString::new(k).unwrap().as_ptr());
| ------------------------ ^^^^^^ this pointer will be invalid
| |
| this `CString` is deallocated at the end of the statement, bind it to a variable to extend its lifetime
...
340 | f!(getpwnam, getpwuid, uid_t, Passwd);
| ------------------------------------- in this macro invocation
|
= note: pointers do not have a lifetime; when calling `as_ptr` the `CString` will be deallocated at the end of the statement because nothing is referencing it as far as the type system is concerned
= help: for more information, see https://doc.rust-lang.org/reference/destructors.html
= note: `#[warn(temporary_cstring_as_ptr)]` on by default
= note: this warning originates in the macro `f` (in Nightly builds, run with -Z macro-backtrace for more info)
```
There doesn't seem to be an actual problem in this case, as the pointer is
only used within the statement.
