[Debian-med-packaging] Bug#860652: snap-aligner: FTBFS on i386: SNAPLib/SortedDataWriter.cpp:338:70: error: no matching function for call to 'max(long unsigned int, _int64)'

Source: snap-aligner
Version: 1.0~beta.18+dfsg-1
Severity: serious

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.
