today I released OpenOrienteering Mapper 0.8.1. Now you have the
following options for fixing bug#876934:
a) Update to 0.8.1.
0.8.x builds successful with proj-5.0.0 and gdal/libpoppler for Debian
Testing on build.opensuse.org. It also builds reproducible for openSUSE
b) Disable GDAL when building openorienteering-mapper-0.7.0. This stops
the crashes from a ODR violation caused by a duplicate symbol named
pulled in by libgdal from libpoppler.
