// A declaration inside a function can sometimes escape (see implementation of
|
|
// MACRO), and while such a declaration may look like it's independently used
|
|
// here, the only way to make contact with it is through its containing
|
|
// function.
|
|
// Since we must have a declaration of _the function_ in order to call it, the
|
|
// contained declaration will have followed along and we can ignore any direct
|
|
// uses of the contained decl.
|
|
// This used to lead to the contained declaration being fwd-decl used, and IWYU
|
|
// crashing when trying to format a printable forward-decl. Ignoring it
|
|
// completely avoids that malfunction.
