A new version of iscan is out. I'll create a PR for it along with the patch from bug 687066 since it doesn't appear the new version fixes that problem.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=09ad8b4a33b46cd744018d3569deb8d42e5fe47f commit 09ad8b4a33b46cd744018d3569deb8d42e5fe47f Author: Matthew Schultz <mattsch@gmail.com> AuthorDate: 2019-09-19 17:16:11 +0000 Commit: Joonas Niilola <juippis@gentoo.org> CommitDate: 2019-09-21 15:35:33 +0000 media-gfx/iscan: 2.30.4.2 version bump Closes: https://bugs.gentoo.org/693994 Signed-off-by: Matthew Schultz <mattsch@gmail.com> Package-Manager: Portage-2.3.69, Repoman-2.3.16 Closes: https://github.com/gentoo/gentoo/pull/12901 Signed-off-by: Joonas Niilola <juippis@gentoo.org> media-gfx/iscan/Manifest | 1 + media-gfx/iscan/files/iscan-2.30.4.2-sscanf.patch | 21 +++ media-gfx/iscan/iscan-2.30.4.2.ebuild | 152 ++++++++++++++++++++++ 3 files changed, 174 insertions(+)
