Comment(by strk):

 Note that the WKT you report as the "old result" is invalid, could you re-
 paste it wrapping it within three curly brackets (it's the syntax for
 preformatted text) ?

 My results of 1.5 are specifically from 1.5.9-svn. The number of points in
 the result are the same (so same number of arcs). The coordinates aren't
 all the same, but the furthest points (hausdorff distance) are 1e-10
 apart.

 Difference in length of the two results is computed to be around 4e-12.
