// pretty-expanded FIXME #23616


// run-pass
#![allow(dead_code)]

// Tests for a previous bug that occurred due to an interaction
// between struct field initialization and the auto-coercion
// from a vector to a slice. The drop glue was being invoked on
// the temporary slice with a wrong type, triggering an LLVM assert.
