It start happen only after use recent version of “emscripten”. Im using now “2.0.34” (but tested with others) to keep it updated, but need solve this error.

Download latest pdfium from my branch: https://www.dropbox.com/s/n1bz12hcvif2h0a/artifact-wasm-4692.zip?dl=1
Unzip it: unzip artifact-wasm-4692.zip
Untar it: tar -xzvf wasm.tgz
Execute: cd "release/node"
Execute: python -m http.server
Open in browser: http://localhost:8000/?debug=1
Execute on browser console: FPDF.Init()

Expected behavior

I tried all optimization levels, but still failling.

My stacktrace:
