Hi
To visualize a large terrain i tried the OpenSG
contrib source TildeTerrain. Everything works fine but
when i want to use more than one texture for my
terrain with
MaterialPtr mat =makeTerrainTexture("filename.jpg");
tiledTerrain->getMFHeightTextures()->push_back(mat);
i get segmentation faults during execution.
Especially after i crossed getSizeROI()+getSizeROI()+1
tiles.
I used gdb for debugging, but the backtrace differs a
lot from test to test.
For example:
Program received signal SIGSEGV, Segmentation fault.

Perhaps someone know the problem and could give me a
hint.
