<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I found a crash in the OGR code due to freeing up the target
OGRSpatialReference object that is created by the OGRCoordinateTransformation
class when calling OGRCreateCoordinateTransformation. The crash occurred when
the geometry transform method assigned the “target” OGRSpatialReference
object that was created by the transformation object. When I destroyed the
transformation object the OGRProj4CT destructor destroyed the OGRSpatialReference
and the geometry was then pointing to deleted memory. The next time the geometry’s
SRS object was used I would get a crash. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>It seems like the problem could be fixed two ways. Either
the geometry clones the OGRSpatialReference object instead of assigning it, or
the OGRCoordinateTransformation object looks at the reference count of the target
OGRSpatialReference object before deleting it. </span></font></p>
