[Lucas Nussbaum]

Source: ruby-concurrent-ext
Version: 1.0.5-1
Severity: serious
Justification: FTBFS on amd64

Usertags: ftbfs-20200225 ftbfs-bullseye

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

This rebuild was done by building only architecture:any binary packages
(binary-arch target of debian/rules).

Relevant part (hopefully):

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
