MapGuide 3.0: apache child abort on evaluating distance between MgPoints

[gabrimonfa]

Mapguide 3.0 on Centos 6 (32bit)

In our code we need to evaluate the distance between two (valid) MgPoints. We use MgPoint::Distance function. Our code does not complete, apache child aborts.

apache log shows

httpd: GeometryComponentFilter.cpp:34: virtual void geos::geom::GeometryComponentFilter::filter_ro(const geos::geom::Geometry*): Assertion `0' failed.

We probably hit this bug: ​https://trac.osgeo.org/geos/ticket/535

Do you have sample code with example points where the MgPoint::Distance call causes the child abort?

[gabrimonfa]

Sample code that causes abort

$wkt1 = 'POINT (3 3)';
$wkt2 = 'POINT (4 4)';

$wktReaderWriter = new MgWktReaderWriter();
$point1 = $wktReaderWriter->Read($wkt1);
$point2 = $wktReaderWriter->Read($wkt2);
$distance = $point1->Distance($point2, null);

error_log('This will not be logged...');

From apache error_log:

httpd: GeometryComponentFilter.cpp:34: virtual void geos::geom::GeometryComponentFilter::filter_ro(const geos::geom::Geometry*): Assertion `0' failed.

In 9010:

Fix #2594. Based on this GEOS ticket (​https://trac.osgeo.org/geos/ticket/469), setting explicit -m32/-m64 flags in CFLAGS/CXXFLAGS/CPPFLAGS/FFLAGS/LDFLAGS before calling the geos configure script.

Running "make check" without these changes reproduces the assertion error.
Running "make check" with this change does not produce the assertion error.

Reopening.

While this fixes geos in isolation, it broke the build system (probably because I changed the oem build order as well)

Fix the build system and confirmed the above PHP code sample works in the beta 2 binaries
