Hi, Something was broken with TNtuple::Draw between 2.21/08 and 2.22/09 on FreeBSD 4.0. When I tried to run tutorials/ntuple1.C, it crashes as follows (with some debugging printfs): root [0] .x ntuple1.C Draw(varexp0 = "3*px+2", selection = "", option = "" nentries = 1000000000, firstentry = 0) Draw(varexp0 = "2*px+2", selection = "", option = "" nentries = 1000000000, firstentry = 0) Draw(varexp0 = "1.3*px+2", selection = "", option = "" nentries = 1000000000, firstentry = 0) Draw(varexp0 = "pz:px>>hprofs", selection = "", option = "" nentries = 1000000000, firstentry = 0) Error function pol2 is not 2-D Error: illegal pointer to class object fpol2 0x0 307 FILE:/usr/home/yasuhiro/root/tutorials/./ntuple1.C LINE:59 *** Interpreter error recovered *** root [1] Secondary argument seems to ran away. It worked well with 2.21/08. regards, -- SHIRASAKI Yasuhiro : Experimental Particle Physics, JLC Team Graduate School of Science, TOHOKU University 980-8578 Japan.
