Dear Rene Brun
I have several shared libs which I am loading from rootlogon.C and to
reproduce the problem one need all this libs. Bellow you can find few
lines making CINT crash

Welcome to ROOT
Loading Int2TString_cpp.so ... succeed

root [0] TileInfo info(2100033)
root [1] Tile04 tile(info.GetTree())
root [2] gROOT->Reset()
root [3] .q
This is the end of ROOT -- Goodbye
*** Break *** segmentation violation
Generating stack trace...
I would like to know why CINT crashes after .q when gROOT->Reset() was
passed without problems.
Thanks,
