Source: blasr
Version: 5.3+0-1
Severity: serious
Tags: stretch sid
User: debian-qa at lists.debian.org

Justification: FTBFS in stretch on i386

Hi,

During a rebuild of all packages in stretch (in a stretch chroot, not a
sid chroot), your package failed to build on i386.

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.
