<pre>The ChakraCore.yaml/ChakraCore/test/fieldopts/objtypespec-newobj-invalidation.1.js test changes the prototype of a constructor function and expects new instances to inherit the new prototype. However, it does not appear to succeed at doing this.
Some details:
1. The issue appears to be racy. it's not easily reproducible on demand though it happens a lot on the bots, and I can reproduce it locally sometimes.
2. If I disable inlining and DFG compilation, I can't seem to reproduce it (assuming (1) above is not interfering).
3. If I disable the concurrent JIT, I can't seem to reproduce it (assuming (1) above is not interfering).
4. If I add options to dump disassembly, etc, I can't seem to reproduce it (assuming (1) above is not interfering).
The failing test output:
