See log here https://buildd.debian.org/status/fetch.php?pkg=rust-wasm-bindgen-macro-support&arch=ppc64el&ver=0.2.33-1&stamp=1549258418&raw=0

The same issue is reproducible with the rustc binary from here, but one needs to first work around #58334/#57345 by building your cargo, e.g. the Debian cargo package works.

Stack traces, but locals are optimised out:

Same problem with rustc 1.31.0 and wasm-bindgen git HEAD (9e40a6d02b8bd67fe9ed5e19e327138490ffe979).

Still happening with version rustc 1.36.0-nightly (963184bbb 2019-05-18).

Hmm, this looks like it's related to #42476 perhaps?
