<pre>On ARM64 bots, we started seeing failures running
mozilla-tests.yaml/ecma/FunctionObjects/15.3.1.1-3.js.mozilla-ftl-eager-no-cjit-validate-phases
mozilla-tests.yaml/ecma/FunctionObjects/15.3.2.1-3.js.mozilla-ftl-eager-no-cjit-validate-phases
mozilla-tests.yaml/ecma/FunctionObjects/15.3.5-1.js.mozilla-ftl-eager-no-cjit-validate-phases
Below is the log output for one of the failures. Possibly a RELEASE_ASSERT.
