Root 6.26/04 crash with Proxies

Roofit and RooStats
1

Dear Experts,
I am struggling with root 6.26/04 version. When I open a workspace (whatever workspace, created with older root version as well as the 6.26/04 itself) and I try to Print(“v”) whatever objects that has “Proxies”, at that level I just have a crash. I copy-paste below the full error that I see.
Do you have any kind of explanation on why this is happening?

Thank you very much.

Best

Chiara

Hi @carcange ,

and welcome to the ROOT forum! Could you check whether the problem is still present in v6.26.06?

If yes, please provide a minimal, self-contained reproducer that we can run to debug the issue on our side. @jonas or @moneta might be able to comment further.

Cheers,
Enrico

Dear Enrico,
thank you very much for your answer. Unfortunately I met the same problem also with the v6.26/06 version. It seems that I cannot upload a file or put a link as new user. Is there another way to share a content?
Thanks again.

Chiara

Ciao Chiara,

you should have permissions to post links and files now. Otherwise https://cernbox.cern.ch might be an option.

Cheers,
Enrico

Ok, it seems that it works now, thanks!
I just uploaded the simplest workspace where I saw this issue on this path:
/eos/user/c/carcange/ws_XS.root
you should be able to access.
In this particular one I saw it for sure in the RooAddPdf and in the RooFormula, instead in the RooSimultanouesPdf seems to not appear. So I really have no idea to what it could be related.
Thanks again.

Best

Chiara

Hi @carcange ,

this issue is [RF] verbose printout of some RooFit classes broken · Issue #10385 · root-project/root · GitHub . It has been fixed in ROOT’s master branch (future v6.28) and there is also a backport for the 6.26 branch (here). I can confirm that the issue is present in v6.26.06 but not in the current v6-26-00-patches branch (future v6.26.10).

In other words: you are hitting a real issue, which has already been fixed, but there have been no ROOT releases that contain the fix so far. You can pick up a nightly build if you need a ROOT version that contains the patch, otherwise we plan to release v6.26.10 very soon.

I hope this helps!
Enrico
