Crash with TGeoManager::AddMaterial()

Dear all,
I don’t know with my very simple program crashes.
Could someone explain me the reason?

The program is compiled with the following command:
g++ test.cpp -o test -Iroot-config --incdir -Lroot-config --libdir -lGeom -lCore

When I try to run it, I get:

Info in TGeoManager::TGeoManager: Geometry geo, geo created

*** Break *** segmentation violation
