Subject: [PATCH] Fix crash when btSoftBody collides with
 btBvhTriangleMeshShape inside a btCompoundShape

- The triBody->getCollisionShape() returns the btCompoundShape again, which does not implement the btConcaveShape interface required
- The crash happens when processAllTriangles is called below
