Seg fault while accessing data created in another class

[jmadsen]

In my main I have:

Volume* myVolume = new Volume();
Geometry* myGeometry = new Geometry();
DataHandler* myData = new DataHandler();

and after the volume and geometry data is put into maps I call:

myData->SortAllData();

which is causing a seg fault at:

std::map<int,std::vector<std::string> > geomData = geometry->GetAllData();

where I declared:
Geometry* geometry;

to access the function in my geometry file:

std::map<int,std::vector<std::string> > GetAllData() { return all_the_geometries ;};




When I do the function call in my main program it works no problem but when I do the function call in my data_handler file I get a seg fault.

I believe all the pointers are defined properly and I included all the files. Any idea what I am missing?

Volume* myVolume = new Volume(); sigh, ¿Is there a good reason to do that instead of Volume myVolume; ?

Your presentation is confusing. ¿Could you post the calls in main and data_handler? (with a little context, please)
