Bug ID: 170390
Summary: WebAssembly: several tests added in r214504 crash when
building with GCC
Product: WebKit
Version: WebKit Local Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Keywords: Gtk
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: cgarcia at igalia.com

The pattern foo->bar([f = WTFMove(foo)]); crashes when building with GCC, I assume the move happens before the foo is used to invoke the function.
