crash when using btHeightfieldTerrainShape + btCollisionObject::CF_CUSTOM_MATERIAL_CALLBACK + btAdjustInternalEdgeContacts without calling initializePolyhedralFeatures()

[GoogleCodeExporter]

What steps will reproduce the problem?
1. replace the files DemoApplication.cpp + TerrainDemo.cpp
2. compile and run the terrain demo 
3. shoot a box

What is the expected output? What do you see instead?
crash happen

What version of the product are you using? On what operating system?
trunk (rev 2460)

Please provide any additional information below.

The crash happens in btAdjustInternalEdgeContacts() because this function 
expect the temporary triangle shape (used for heightfield shape triangles) to 
either be of type btScaledBvhTriangleMeshShape or btBvhTriangleMeshShape.

The following line therefore returns a bad pointer:

btTriangleInfoMap* triangleInfoMapPtr = (btTriangleInfoMap*) 
trimesh->getTriangleInfoMap();
