Dear all,
I have noticed that when running my ideal deco macro
it gets to segmentation fault caused by a problem with
ROOT::delete_TFile(void*) ()
or by PndHyp::Streamer get the following error message

here is the output,
[lorente@himster Alicia]$ root -l hit_hypmvd.C

Does someone has an idea?
What is the meaning of the Streamer.
I know it is related with the version of the dictionary created for root.
Is there a maximum number for that?

do we still need the PndXXGeo PndXXConFact?

please to reproduce the error go to macro/hyp/Alicia

there you can find a README.txt file where the information needed to run
the simulation is given.

thank you in advance

Alicia S.

In PndHyp destructor you should delete the objects you have created. In your case you are not deleting a TFile, a TTree and a TRandom. I suppose that is the reason.

Hi ste,
unfortunately I'm getting the same problem.

what is the maximum number for the streaming of ClassDef?

9 ? 11?

There is no maximum number of ClassDef, if this is what you are asking.

Hi Alicia,

a streamer is the method of the dictonary of a ROOT class which takes care about persiting an object to file (as far as I understand). When writing the class interface you can actually mark member variables which shall not be written (e.g. temporary objects created when the class is created) with a comment like

int member; //!

I noticed that the member variable fFile (see https://subversion.gsi.de/trac/fairroot/browser/pandaroot/trunk/hyp/PndH yp.h#L226) and perhaps others might be automatically streamed since they are not marked to be ignored by the streamer.

In summary, you could try to put a "//!" like

226	  TFile *fFile; //!
227	  TTree *ft; //!
228	  TClonesArray *fEvt; //!

and try whether this helps (just an idea, I'm not at all sure Wink

).

Best,
Klaus

Hi again,
ok I think I have found a way by initialising
the pointers to the TObjects within the class constructors, and
calling the corresponding delete functions within the destructors. Embarassed

Hopefully, I can come back to my previous happy life again
more wiser and with additional white hairs.

regards

Alicia.

Well,

this is how C++ works... If you don't do it you produce memory problems Smile
