[maraf]

@radekdoulik Do you know what changes in emsdk for 8.0 that EXPORT_ES6 now produces a warning?

[pavelsavara]

I think EXPORT_ES6 is linker flag, not compiler flag.

[lewing]

There are actual errors here that are not related to the ES6 warning

[pavelsavara]

it's probably warning treated as error, which will really stop the build. It should be easy to fix

[carlossanlop]

@pavelsavara @lewing can you please adjust the ErrorMessage to what you think would be more appropriate?

[pavelsavara]

This is probably OOM on AOT compilation and sigkill.

[pavelsavara]

We could try to fix it by backporting https://github.com/dotnet/runtime/pull/115624
