Description Robert Jenner 2021-08-25 15:47:46 PDT 
It looks like the tests were added here:
https://trac.webkit.org/changeset/281513/webkit

and have been flaky failing with the following assertion ever since:

ASSERTION FAILED: !m_needExceptionCheck
stress/intl-enumeration.js.bytecode-cache: ./runtime/VM.cpp(1485) : void JSC::VM::verifyExceptionCheckNeedIsSatisfied(unsigned int, JSC::ExceptionEventLocation &)


Build: 
https://build.webkit.org/#/builders/100/builds/742


In their history it does appear that they all fail at the same intervals as well:

Landing since it only affects on debug jsc stress tests, which does not exist in EWS
