A map causes a crash

[neivv]

The following map will cause scm-extractor to throw an uncaught exception with the following message:

C:\Jotakin\src\scm-extractor\index.js:596
    if (b < this._hashTable.length && this._hashTable[b].blockIndex === 0xFFFFFFFF) {
                                                        ^

(It also doesn't work in 1.18.8, but 1.16.1 loads it fine)
