Bug#877168: nmu: gtk-d_3.6.5-2

nmu gtk-d_3.6.5-2 . amd64 . unstable . -m "Rebuild against libphobos2-ldc74"

tilix was built with the latest version of ldc and as a result is linked
against libphobos2-ldc74. It also links against libvted-3-0, which was
not compiled with the newest ldc version yet, so still links against
libphobos2-ldc72. Apparently mixing libraries this way is not supported
and as a consequence tilix fails to start, see #876479:

$ tilix
Fatal Error while loading '/usr/lib/x86_64-linux-gnu/libdruntime-ldc.so.72':
	The module 'core.atomic' is already defined in '/usr/lib/x86_64-linux-gnu/libdruntime-ldc.so.74'.

Rebuilding gtk-d (which provides libvted-3-0) against libphobos2-ldc74
seems to fix the error.

CCed the D developers. It would be nice if such situations could be
avoided in the future. Maybe you have some ideas how to achieve that.

The situation is a mess:
https://packages.debian.org/sid/tilix
https://packages.debian.org/sid/libvted-3-0

There is no consistency wrt to which version of libphobos2-ldc the
binaries are linked against.

Michael
