esbuild-plugin-meta-url + quickjs-emscripten aborts

[exoego]

Background

I am using https://github.com/justjake/quickjs-emscripten with esbuild.
It works fine until quickjs-emscriptedn v0.24.0.

quickjs-emscripten v0.25.0+ started using import.meta.url, something like new URL("emscripten-module.wasm", import.meta.url).href.
Which is, unfortunately, not supported by esbuild yet: evanw/esbuild#795
Some users (including myself) reported it in justjake/quickjs-emscripten#151

I tried esbuild-plugin-meta-url and found an issue.

Repro

I made a repro here: https://github.com/exoego/quickjs-emscripten-esbuild-repro

git clone https://github.com/exoego/quickjs-emscripten-esbuild-repro.git
npm ci
npm run build

Issue

Running esbuild with meta URL plugin aborts due to heap out of memory:

$ node esbuild.mjs src/runtime/lambda.ts dist/reactor-runtime/index.js

I gave a try on large heap but did not help: node --max-old-space-size=24000 esbuild.mjs which hangs.
