Much better!

The cause of the fatal error was:

Nice, the full log is here

I get an expired URI error message. What are you high level conclusions?

[lesteve]

I'll merge the PR so that at least we have a daily build and we can look at the errors.

I did not have high-level conclusions, there were some Cpp exceptions errors that I had never seen before, so that may be fixable.

I assume the Pyodide build was generated by @hoodmane once and is not going to be updated regularly. In an ideal world the debug build would be updated regularly (or there would be artifacts we could download somewhere).

[lesteve]

Also to be honest, the hope is that some of the errors may disappear when we switch to OpenBLAS pyodide/pyodide#3331, so it is probably better to try to switch to OpenBLAS first, before trying to investigate these kind of issues.
