   1 An `export_name` attribute contains null characters (`\0`).
   2
   3 Erroneous code example:
   4
   5 ```compile_fail,E0648
   6 #[export_name="\0foo"] // error: `export_name` may not contain null characters
   7 pub fn bar() {}
   8 ```
   9
  10 To fix this error, remove the null characters:
  11
  12 ```
  13 #[export_name="foo"] // ok!
  14 pub fn bar() {}
  15 ```
