SUMMARY: AddressSanitizer: 16 byte(s) leaked in 2 allocation(s).

```

Start by reproducing the JavaScript POC on Ubuntu 18 with an AddressSanitizer build and compare its leak report. The payload provides no source file or test location, so trace the reported allocation stack through ChakraCore to identify the leaked objects. Done means the reproducer no longer reports the two allocations as leaks.
