+error: getting the inner pointer of a temporary `CString`
+ --> $DIR/lint-temporary-cstring-as-param.rs:9:45
+ |
+LL | some_function(CString::new("").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
+ |
+ = 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: the lint level is defined here
