   Hello rooters,

    I am using ROOT version 3.05 CVSed yesterday on LINUX. 
 I am tryingto do a fit to a graph with a function other than
GraphFitChisquare().  Attached is a script that will work when ACLiC
compiled (note that GraphFitChisquareNoEX is just GraphFitChisquare for
debugging).  But if GraphFitChisquareNoEX is compiled and testfit is in
interpreted mode, I get a SegV.  I can trace it to the line  

   fu   = grF1->EvalPar(x,u);

 and it seems that the segV is called because of u.  If I do a
cout<<u[0]<<endl; in the function, I get a segV at that point.
