Hello,

> ERROR: In procedure make-stack:
> Attempt to suspend fiber within continuation barrier

Turns out "par-map" call does not seem suspendable, even though I'm not
sure why. Maybe Ludo can help here :) ?

This is fixed with: 761443bca6178b4ac299a8bd368d1cac4abda5f8.

Thanks,

Mathieu

the specification is:

    (#:build-outputs . ())))

It looks like adding a second input, creates an exception during inputs
fetching.

Thanks,
