Building markdown failed while validating input.

[OrangeTux]

I tried to compile the markdown example, but unfortunately compilation fails.

$ wasm-pack --version
wasm-pack 0.9.1
$ cargo --version
cargo 1.41.0 (626f0f40e 2019-12-03)

Here are the steps to reproduce. Not that I didn't copy full logs:

Fatal: error in validating input
Error: failed to execute `wasm-opt`: exited with exit code: 1
  full command: "/home/developer/.cache/.wasm-pack/wasm-opt-4d7a65327e9363b7/wasm-opt" "/home/developer/projects/wasmtime-demos/markdown/pkg/markdown.wasm" "-o" "/home/developer/projects/wasmtime-demos/markdown/pkg/markdown.wasm-opt.wasm" "-O"
To disable `wasm-opt`, add `wasm-opt = false` to your package metadata in your `Cargo.toml`.

I've tried the suggestion and modified the Cargo.toml and added the following lines:

[package.metadata.wasm-pack.profile.dev]
wasm-opt = false

But that didn't help

[daubaris]

I have the same issue. Except that when I add

[package.metadata.wasm-pack.profile.release]
wasm-opt = false

I get another error:

Error: multiple tables: tables count must be at most 1 (at offset 425)

It is also worth mentioning that nothing was modified besides the part mentioned above and updated crate versions.

Similar behavior occurs when trying to port simple modules with wasm_bindgen. Could anyone provide any insights?

I'm going to now that we've temporarily removed interface types support, but stay tuned to bytecodealliance/wasmtime#677 for future updates!
