any thoughts @fitzgen or @alexcrichton ?

[ashleygwilliams]

getting these on master now too https://travis-ci.com/rustwasm/wasm-pack/jobs/216579394#L538

[ashleygwilliams]

per in chat convo with @fitzgen- looks like we are testing on the contents of the error message.. which may have changed https://github.com/rustwasm/wasm-pack/blob/master/tests/all/build.rs#L197 i'll run it manually and see.

I don't see any difference between the JS glue when build with debug-js-glue = true or debug-js-glue = false.

[fitzgen]

I verified via strace that wasm-pack is not invoking wasm-bindgen with the --debug flag regardless whether debug-js-glue is set or not. Furthermore, if I manually invoke wasm-bindgen with --debug then the move assertion does appear in the JS glue.

[fitzgen]

False alert: I was building with the release profile and the test/configuration was for the dev profile.

wasm-pack is passing --debug to wasm-bindgen but wasm-bindgen is no longer emitting the assertion.
