It looks like something is wrong. Does it happen for the same coordinate
values or random?
It would be helpful if you could prepare simple test case, a minimal
code snipped (perhaps as a ticket at the http://trac.osgeo.org/gdal/)
presenting how do you use the OGR code, input data and what output you
get. Then it will be possible to try to reproduce this problem and debug.
