            Bug ID: 221557
           Summary: JSC stress test
                    stress/copy-data-properties-fast-path.js.default fails
                    on s390x and ppc64le
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at gnome.org

This new test from bug #221454 is broken on s390x and ppc64le, but works on x86_64 and aarch64. This is a little odd since these architectures have little in common. All architectures have JIT disabled and cloop enabled. The test is:

//@ runDefault("--slowPathAllocsBetweenGCs=4", "--watchdog=100", "--watchdog-exception-ok")

function foo() {
  let { ...r } = { xx:0 };
  foo();
}
foo();

How is that recursion supposed to end? Anyway, on these architectures it doesn't, the error is:

stress/copy-data-properties-fast-path.js.default: Exception: RangeError: Maximum call stack size exceeded.
