@martenole @davidrohr the crash in mat. query in #4297 was because of multithreading: most of TGeometry operations are not thread-safe. I've protected TGeo calls by mutex and enabled material corrections in TRD, but for production benchmarks, we should only LUT (which is thread-safe) since the TGeo, apart from being extremely slow, with mutex may make the multithreading meaningless.
