Comment(by strk):

 Interesting enough, like GEOS also JTS fails buffering this input with the
 original precision.
 Odd, as the input is a very simple rectangle with a side of 3.5 units (a
 linestring) being buffered with a distance of 1 unit.
 Full coordinates are in the order of 1E6 units.

 The exception thrown (by both GEOS and JTS) when attempting the operation
 on the orginal input is:

 TopologyException: assigned depths do not match [ (1676339.4415330526,
 4847442.824250799, NaN) ]

GEOS (Geometry Engine - Open Source) is a C++ port of the Java Topology Suite (JTS).
