            Bug ID: 142277
           Summary: [ARM] stress/cached-prototype-setter.js.no-llint fails
                    intermittently on Aarch64 Linux
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

It fails in ~33% of the test runs with the following log:

Exception: Error: FAIL: 'x' setter was not called.
cached-prototype-setter.js:18:24
global code at cached-prototype-setter.js:19:3

It seems it is a DFG JIT bug, because it passes always with 
the same configuration and additional useDFGJIT=false
