Organization and simultaneous fits: RooFit memory tracing debug tool

 
[#0] WARNING:InputArguments -- The parameter 's' with range [-10, 10] of the RooGaussian 'g' exceeds the safe range of (0, inf). Advise to limit its range.
List of RooFit objects allocated while trace active:
 class RooSharedProperties count = 1 sizeof = 56 total memory =  0.00 Mb
