WebGL example fails with unexpected section: <unknown> @+2824

[bwasty]

The WebGL Example (Guide Page) fails with this error (Browser console):

CompileError: AsyncCompile: Wasm decoding failed: unexpected section: <unknown> @+2824

I also get the same error when I copy the code to my project that is based on wasm-pack-template.

Interesting, I'll try to repro it. What version of Webpack and webassemblyjs are you using? (Check npm ls).

[bwasty]

webpack@4.29.4
@webassemblyjs/ast@1.8.2 (same version also for all other webassemblyjs packages)

Before upgrading to webpack@4.29.4 I had another similar error - the same as here: #1251.

@bwasty can you test out the latest version of wasm-pack and NPM dependencies as well to see if the issue is fixed now?

[bwasty]

@alexcrichton No change with

wasm-pack 0.6.0

wasm-bindgen v0.2.37

webpack@4.29.5
@webassemblyjs/*@1.8.3

[alexcrichton]

Oh sorry @bwasty I misunderstood, this is indeed published live and I can see it myself!

@xtuc it looks like webpack may be producing an invalid JS wasm file?

[xtuc]

Indeed, Webpack's transformation breaks the Wasm module.

@bwasty This will work if you remove the start. We are working on a fix now at xtuc/webassemblyjs#493

[alexcrichton]

Looks like this is now fixed, thanks @xtuc and @sendilkumarn!
