Re: Weak tables harmful to GC?

[Ricardo Wurmus]

Hi Ludo,

does this apply to the latest release of Guile 2.2.2?  I’ve created this
package definition:

--8<---------------cut here---------------start------------->8---
(define-public guile-2.2-awesome
  (package (inherit guile-2.2)
    (name "guile-awesome")
    (source (origin (inherit (package-source guile-2.2))
       (patches (list 
"0001-Remove-weak-tables-and-revert-to-weak-hash-tables.patch"
                      
"0002-Keep-weak-hash-table-item-count-consistent.patch"))))))

--8<---------------cut here---------------end--------------->8---

But the build fails:

--8<---------------cut here---------------start------------->8---
