⏯ How to reproduce:

1. Use Node 10
2. git clone --branch 21-add-typescript-support git@github.com:theqp/MyEtherWallet.git
3. Change typescript to 4.2.2 (it would work otherwise)
4. npm i
5. echo "" > package-test.js && NODE_OPTIONS="--max-old-space-size=4096" npm run build
6. Wait for the crash :D

Inizia riproducendo la build di Node 10 usando il branch MyEtherWallet indicato, TypeScript 4.2.2 e il comando npm run build. Esamina le voci dello stack parseList e parseSourceFileWorker in node_modules/typescript/lib/typescript.js, insieme alla configurazione memoryLimit di ForkTsCheckerWebpackPlugin. Il lavoro è completato quando la build 4.2.2 termina senza esaurire l'heap JavaScript e la regressione rimane coperta.
