Ben, is there a way to write a similar test for the original bug without consuming as much memory?

It could, but the problem is bigger with run-javascriptcore-tests, because it runs each test with different configurations parallel, for example: Running jsc-layout-tests.yaml/js/script-tests/stringimpl-to-jsstring-on-large-strings-2.js.layout Running jsc-layout-tests.yaml/js/script-tests/stringimpl-to-jsstring-on-large-strings-2.js.layout-no-llint Running jsc-layout-tests.yaml/js/script-tests/stringimpl-to-jsstring-on-large-strings-2.js.layout-no-cjit Running jsc-layout-tests.yaml/js/script-tests/stringimpl-to-jsstring-on-large-strings-2.js.layout-dfg-eager-no-cjit It means that 4 copy of the same memory consuming test can run in the same time.

The problem is this bug only crashed JSC when dealing with strings larger than 2gb. We need bugs like this to be covered but we can't have these tests break other tests. Ossy, is there any way to make some tests sequential instead of running in parallel with everything else? Any other idea to solve this?

Any other idea to solve this? run-jsc-stress-tests uses GNU make (-jXXX) to run tests parallel, there is no way to prevent running them parallel without giant hacks in prepareMakeTestRunner: https://trac.webkit.org/browser/trunk/Tools/Scripts/run-jsc-stress-tests#L1697 Do we really need to run these test in all configurations? - default - no-llint - no-cjit - dfg-eager-no-cjit I suggest skipping them until we find a better fix.

I'll fix there too before landing.
