#2410 closed defect (fixed)

ST_CurveToLine drops first vertex of a straight curve

Reported by: strk Owned by: strk
Priority: high Milestone: PostGIS 2.0.4
Component: postgis Version: 2.0.x

Description

Passing a straight line to ST_CurveToLine:

CIRCULARSTRING(0 0,1 0,2 0)

Results in a linestring missing first vertex and having a duplicated second vertex:

LINESTRING(1 0,2 0,2 0)

1.5(.9) is _not_ affected, 2.0 and 2.1 are affected.

I guess 2.1.0 could wait for a fix to this. I have a fix locally, which doesn't change any of the existing regression tests results.

See also #2407 which is the context in which I've found this one
