ChakraCore branch master cbb9b was discovered to contain a segmentation violation via the function Js::EntryPointInfo::HasInlinees().
Branch: `master`
Commit: `cbb9b101d18e4c1682ca39a52a201d8e4241ea17`
POC is:
```
async function f1() {
    await null;
    throw WScript.f2a(f1());
}
f1();

async function f2() {

    async function f2a() {
        throw "err";
    }

    async function f2b() {
        try {
            var p = f2a();
        } catch (e) {
            console.log("caught " + e);
        }
    }

    async function f2c() {
        var p = f2a();
    }

    f2b();
    f2c();

In release build
`./build.sh --sanitize=address --static -j` 
I get:
