Convex Hull generator crashes

Convex Hull generator crashes

Hi, we have integrated convex hull generation into our build pipeline. Off the couple of hundreds objects we have, two bounced back with a program crash in the convex hull generator. I stored the geometry in an hkGeometry and applied a weld to it, then stuffed it into the convex hull generator. Here is the code I used to save the file

			hkGeometry geo; // Filled with my data

			hkOArchive os("broken.dat");

			os.write32( geo.m_vertices.getSize() );

			for ( hkInt32 i=0; i< geo.m_vertices.getSize(); ++i )
				os.writeFloat32( geo.m_vertices[i](0) );
				os.writeFloat32( geo.m_vertices[i](1) );
				os.writeFloat32( geo.m_vertices[i](2) );
				os.writeFloat32( geo.m_vertices[i](3) );

			os.write32( geo.m_triangles.getSize() );

			for ( hkInt32 i=0; i< geo.m_triangles.getSize(); ++i )
				os.write32( geo.m_triangles[i].m_a );
				os.write32( geo.m_triangles[i].m_b );
				os.write32( geo.m_triangles[i].m_c );

and this is my call to the hull generator:

		hkStridedVertices sVerts;
		sVerts.m_vertices = (const hkReal*) geo.m_vertices.begin();
		sVerts.m_striding = sizeof( hkVector4 );
		sVerts.m_numVertices = geo.m_vertices.getSize();
		hkGeometryUtility::createConvexGeometry( sVerts, geoConv);

I can't debug this since it crashes deep down in the havok, around buildIndices or something. I attached the file to a second, private post.
