Hi Patrick, I fixed the problem you are reporting with fitting in August in version 3.02. This was an unfortunate problem with the TF1 copy constructor called when making a copy of the fitted function to be stored in the histogram list of functions. When you specify the option "N" (do not store the fit), the problem disappears. However, in this case, you should not call, eg TF1 *ffi=(TF1 *)h1->GetFunction("lastShape") the pointer ffi, in this case, will be null and you will get a crash when calling GetChisquare. The only thing that I can suggest is to use version 3.02. We are currently at version 3.02/02 and expect to make a production release by the end of November (+- one week).
