Builds failing with 'unsupported custom section: '.debug_info''

[dhardy]

Recent Rand builds seem to be failing with this error:

$ cargo --list | egrep "^\s*web$" -q || cargo install cargo-web
$ cargo web test --target wasm32-unknown-unknown --nodejs --features=stdweb
warning: debug builds on the wasm32-unknown-unknown are currently totally broken

note: Run with `RUST_BACKTRACE=1` for a backtrace.

(Example)

Any idea what's up? (It could be due to outdated versions of cargo-web installed in our CI cache due to avoiding the update, I suppose.)

I have the same on clean Ubuntu 17.10 VM.

• cargo-web 0.6.13
• stdweb 0.4.7
• rust nightly

Thanks for the report! Should be fixed in 0.6.14.
