I tested it again on ToT, stress/arguments-inlined-exit-strict-mode.js.default-ftl doesn't fail now ... but something is changed, because FTL JIT isn't run at all for this test now. Of course FTL runs for the "ftl-eager-no-cjit" case ... but this test always passed in the passed. So the bug can be valid, but isn't triggered anymore.
