Tree with events

sapinski · November 27, 2010, 4:53pm

Hi,
I’ve been successufully using a TTree to store Event objects from Geant4 simulation. That was with root version up to 5.22 on SLC4. Now I belive I have a problem. The moment I call
event = new Event();
in Geant4 code I’m getting memory corruption:
*** glibc detected *** bin/Linux-g++/MQ: malloc(): memory corruption: 0x0000000013d22920 ***

Is the new compiler more rigoristic?
Could you please have a look if I’m not doing anything stupid in the Event.h and Event.cxx (attached).

Cheers,

Mariusz

As a quick test, I simply did

root > .L Event.cxx+ root > Event *e = new Event; root > e->Clear(); root > e = new Event;
and it seems to work. I cannot go further without having your test program.
My suggestion is to run under valgrind.

It is difficult to provide you with a test program. I’ll try at least to send you the valgrind output (it is a perto of it, but I guess the beginning is valid):

I would guess that Event.h has been changed but not all the source file and library that uses have been recompile since … or they are seeing 2 very different version of the file Event.h … (I say that because the object is allocated in RootInterface::RootInterface() and immediately there after a constructor is trying to access past its end …

Cheers,

Hi,

  I think have actually made it working by removing all variables like:

char fType[10];
and function referring to these variables. I’m still not sure what the error really was, but since that I have no more memory leaks according to valgrind. Maybe there is something in gcc 4.3 which is more strict about these kind of variables than in gcc 3.2?

Cheers,

[quote]Maybe there is something in gcc 4.3 which is more strict about these kind of variables than in gcc 3.2?[/quote]There should not be. It probably either depend on the way you initialize them (assuming that it is not in fact a build problem/discrepancy).
