;; Test that we show a warning on an empty local name, and do not crash.
;;
;; The binary contains this, processed by wabt with debug names:
;;
;; (module
;; (func $foo (import "imports" "foo") (param i32)))
;;
;; Wabt emits a name for that parameter, but it is the empty string. See
;; https://github.com/WebAssembly/wabt/issues/1799
;; RUN: wasm-opt %s.wasm 2>&1 | filecheck %s
;; CHECK: warning: empty local name at index 0 in function foo
