-which used to execute successfully, will now panic with a nil-pointer exception:

-package main
-
-import "os"
-
-func main() {
-	f, err := os.Open("nonExistentFile")
-	name := f.Name()
-	if err != nil {
-		return
-	}
-	println(name)
-}
-```
-
-This program is incorrect in that it uses the result of `os.Open` before checking
-the error. The main result of `os.Open` can be a nil pointer if the error result is non-nil.
-But because of [a compiler bug](/issue/72860), this program ran successfully under
-Go versions 1.21 through 1.24 (in violation of the Go spec). It will no longer run
-successfully in Go 1.25. If this change is affecting your code, the solution is to put
-the non-nil error check earlier in your code, preferably immediately after
-the error-generating statement.
