Bug#888173: ruby-sawyer: FTBFS on ruby2.5: can't dump anonymous class

[Miguel Landaeta]

severity 888173 normal
forwarded 888173 https://github.com/lostisland/sawyer/issues/54
thanks

I uploaded ruby-sawyer/0.8.1-3 to sid with the affected tests disabled.
I'll keep this bug open since is clearly not solved.
I also forwarded this issue to upstream.

tags 888173 + confirmed upstream buster sid
owner 888173 !
thanks

The most immediate mitigation for this issue seems to be to disable
the affected tests and report this to upstream.

psych library included in ruby stdlib was updated between ruby2.4 to
ruby2.5, from 2.2.4 to 3.0.0 and it has introduced some breaking
changes.
