// WITH_STDLIB

// This test demonstrates a situation when a reference for a stub local inline function in not inlined
// at the 1st phase of double-inlining. See KT-69470 for more details.
// The test itself is not muted because a special condition was added to `validateIrAfterInliningOnlyPrivateFunctions`.
