segfault from shared_ptrs in ParameterList #235

Closed redeboer closed 5 years ago

redeboer commented 5 years ago

A segmentation fault is caused by shared_ptrs in ParameterList. This happened the moment when ParameterList is destroyed.

To Reproduce I was rewriting the DalitzFit example to use an XML file from the expert system as input instead of a stringstream. The bug was introduced when switching from DalitzPlot to RootPlotData:

ComPWA::Tools::Plotting::RootPlotData plot(kin.getParticleStateTransitionKinematicsInfo(), "rootplot.root");
  plot.writeData(SampleDataSet);
  plot.writeIntensityWeightedPhspSample(Data::convertEventsToDataSet(phspSample, kin), intens);

Environment (please complete the following information):

You can reproduce the error from this branch on my fork.

It happens when you run the JpsiToGammaPi0Pi0 script with Examples/JpsiToGammaPi0Pi0/model.xml as input.
