Package: ftp.debian.org Severity: normal The version of openscad in unstable, 2015.03-1+dfsg-2, is very different than the one in testing both in terms of code and depends. It's never built on armhf/armel and as a result will end up blocking at least the qscintilla2 portion of the gcc5 transition. I think it's better to remove the old binaries on these arch to remove an obstacle to the megatransition and then later arm* can be dealt with by the maintainer/porters.
