double free corruption when trying to compile to emscripten

[zbraniecki]

When compiling this: https://pastebin.mozilla.org/8918190

using: "rustc --target=asmjs-unknown-emscripten hello.rs"
following instructions from https://users.rust-lang.org/t/compiling-to-the-web-with-rust-and-emscripten/7627

I'm getting this crash: https://pastebin.mozilla.org/8918194

Unfortunately that pastebins show up as empty today. Sad 😭 .

I'm going to close this because unfortunately the pastebins are gone
