[ROOT] Strange TTree behaviour

Hi all,
I'm reading a Tree (SDMON) which has been filled.
I'm looking at the fTime variable (stored as a UInt_t in the tree).

If I do :

root [64] SDMON->Draw("fTime","fTime<992093754")
(Int_t)8

Root tells me that there are 8 entries with fTime<992093754

But :

root [65] SDMON->GetMinimum("fTime")
(Double_t)9.92093754000000000e+08

So Root tells me that the minimum value of fTime found in this tree is
992093754

There is a contradiction there... Moreover if I do :
root [68] SDMON->Draw("fTime","fTime==992093753")
(Int_t)1

and then Root makes a Segmentation fault...

Any idea of what happens ???

Thank you

	Cyril Lachaud
