[postgis-devel] Invalid geometry from buffer

[strk]

st_buffer('POLYGON((0 0, 10 0, 10 10, 0 0))', -3, 8);

The above returns a Polygon with a ring containing 0 points.
It is invalid for postgis, and not all functions can deal with that.
For example the canonical text output and area() can't, summary() can.

Martin, does JTS return the same weird polygon rather than a
POLYGON EMPTY ?
