multipolygon set from oraclespatial crash with OGR

[bluecarto@…]

Using Mapserver, I'm having problems encountered when trying to render
multipolygons from oracle with OGR connectiontype. Those polygons are in
opposite well rendered with oraclespatial connectiontype.
 You can find below a SQL snippet that permit to create table records that I
think should allow to identify the bug source. Note that shape 1,4,7 and 8 cause
ogrinfo and mapserver crash.
 The different studied cases try to take account of the many possibilities.
 Shape 7 and 8 are "clones" of the first one, but using counterclockwise order
(as  said in the spatial manual section 2.2.4).

It turns out there was a missing case for 3D multi-polygons.  I have committed
a fix for this which will appear in GDAL 1.2.5.

Thanks!
