What OS are you running on? (e.g. Ubuntu/Debian/etc)

Additionally can you upload the wasm file which causes this segfault?

Oops totally forgot that :joy:

pop_OS! is a derivative of Ubuntu :smile:

Additionally can you upload the wasm file which causes this segfault?

So here is the terminal output:

So from that, I assume I need to get the pkg/wasmboypluginhqx_bg.wasm. Which you can download here.

Let me know if that helps! :smile:

Ok using the release_78 binaries locally myself I can get -O3 to segfault when running over that wasm file. Additionally using the latest release_87 it segfaults. I've opened https://github.com/WebAssembly/binaryen/issues/2273 as an upstream issue.

@alexcrichton Awesome! Thank you very much! 😄 Stoked I can help!

Now that version_89 is released, would it make sense to attempt updating the wasm-opt installer version?

EDIT: That version doesn't seem to solve the problem for me, unfortunately.

@anp i know this is a super late message but did you happen to try version 90? want to release wasmpack1.9.0 soon and do not want to break all linux users

i'm going to close this because i do believe that today's release will fix it. if it does not- please open a new issue!
