Bug#1049662: lodepng: Fails to build binary packages again after successful build
Source: lodepng
Version: 0.0~git20220618.b4ed2cd-3
Severity: minor

Hi,
This package fails to do build a binary-only build (not source) after a
successful build (dpkg-buildpackage ; dpkg-buildpackage -b).
This is probably a clear violation of Debian Policy section 4.9 (clean target),
but this is filed as severity:minor for now, because a discussion on
debian-devel showed that we might want to revisit the requirement of a working
'clean' target.
More information about this class of issues, included common problems and
solutions, is available at
