Segmentation Break

Hi All,
I am running a program in Garfield++. On compilation it shows me error like this

There was a crash.
This is the entire stack trace of all threads:

#0  0x00007f5c70a2eb4c in __libc_waitpid (pid=4795, stat_loc=stat_loc

How to solve it.
Reply will be highly appreciated

Hi,

A crash in TGeoElement::GetElementTable is quite unlikely. Did you make sure that all library you are using (including possibly Garfield++) have been build and linked against the same version of ROOT?

If you did, can you run you failing example under valgrind:valgrind --suppressions=$ROOTSYS/etc/valgrind-root.supp executbale_name [args]

Cheers,
Philippe

You should add the code below to your own code:

TApplication app("app", &argc, argv);
plottingEngine.SetDefaultStyle();

 ------the main body of your code 

app.Run(kTRUE);
