Dear ROOT experts,
My RooFit macro that runs fine in ROOT 5.21.02 crashes in ROOT 5.21.04.
In my macro (see attachement), I use RooDataHist to create PDFs from histograms which I stored in a root file (also attached). Then I create a model from these PDF and use RooMCStudy to do toy MC studies using extended maximum likelihood method. The crash happens at the line where I use RooMCStudy.
I wonder if something important has changed in RooFit from 5.21.02 to 5.21.04 that might cause this problem?
Also, I note that when I try to run the tutorial macros rf801 to rf804 in $ROOTSYS/tutorials/roofit directory. All runs fine in 5.21.02 on lxplus but when I use 5.21.04, two of them crash, ie rf801 and rf803.
For information, I am using ROOT both on lxplus and my Mac computer (10.5.5):
lxplus: /afs/cern.ch/sw/lcg/app/releases/ROOT/5.21.04/slc4_ia32_gcc34
and /afs/cern.ch/sw/lcg/app/releases/ROOT/5.21.02/slc4_ia32_gcc34
on my mac: I am using binaries of ROOT for v5.21.04.macosx105-i386-gcc-4.0
Many thanks. Any help is greatly appreciated.
Best wishes
Teh Lee
