Snapping is terrible. I have to snap up to a tolerance of 6.5...

I reduced the geometries to their most simple expressions:

SELECT ST_Difference(
ST_GeomFromText('POLYGON((
-1120500.00000013 850931.058865365,
-1120500.00000013 851343.388500772,
-1120500.00000013 851342.238600771,
-1120437.08611496 851276.059482963,
-1120500.00000013 850931.058865365
))')
,
ST_GeomFromText('POLYGON((
-1120500.00000013 851253.462787063,
-1120500.00000013 851299.817938382,
-1120492.149841 851293.841788941,
-1120500.00000013 851253.462787063
))')
)

Note that if I remove the second vertice of the first geometry it works...

Want me to fill a ticket?

Pierre
