Confirm, I see a problem compiling closures, this should be the
responsible for the bootstrap to be broken (at least on my case).

Yesterday I've already reduced a small reproducer so I should be on the
good way to understand during the next debug session why this is
happening only on wide-int.

It will be interesting why is working in some configuration and not in
others.
