Mapscript 4.10.0 and 4.10.2 gives segfault with Postgres 8.2 [SEC=UNCLASSIFIED]

[Roppola, Antti - BRS]

Hi all,
 
We're in the process of upgrading from 4.8.1 to 4.10.2 and we are seeing
segfaults
when using PostGIS layers. I've had a look through the bug tracker and
source, the main
difference between msPOSTGISLayerRetrievePK() between 4.8.1 and 4.10.2
appears
to be the following (mappostgis.c revisions 1.66 to 1.77):
 
* Revision 1.71  2006/05/03 22:35:41  pramsey
 * Added schema separation and search path awareness to the
LayerRetrievePK. (towards Bug 1571)
 
Does anyone know if this is a known issue? Is the schema patch likely to
be the source of it?
 
 - I can usually get two or three maps before the application server
dies completely
 - We're using the Java mapscript swig bindings
 - Postgres 8.2 with PostGIS 1.2.0
 - The segfault occurs with 4.10.0 and 4.10.2
 - I have not had a chance to see if the CGI version has the same
problem
 - Reverting to 4.8.1 on the same system works fine, suggesting it's not
a Postgres/PostGIS issue
 - Stack trace included below
 
Thanks,

Antti Roppola
