This looks like an issue in GEOS, not osm2pgsql.
Searching for the error message turns up several threads marking this
issue as fixed in GEOS >= 3.3.3. E.g.
This change in GEOS removes the `shellCount <= 1' assert, that is
triggered on your system:
This leads me to think that the mix of squeeze, wheezy and jessie
packages on your system is the actual cause.
To rule out your esoteric mix of package from different Debian releases,
having a smaller test case than importing a full planet dump would be
most helpful. We can't expect anybody to perform full planet imports to
troubleshoot this issue. I for instance don't have the disk space
available for a full planet import.
If you can pinpoint which OSM objects were being processed at the time
of the failure, reproducing the failure with a smaller extract for the
area should be doable.
Reproducing the issue on a proper jessie system would be even more helpful.
