Crash when trying building a figure

ROOT
1

Good evening,

I successfully ran the MyHitSelector macro which creates and displays histograms in 4 canvas in a PROOF session.

When I wanted to print one of the canva in a figure, by instance in ps, through the canva menu, I have the following crash happening when I just click on the File menu of a Canva [color=#FF0000](see part in red)[/color]

On the other hand, when I call the Print function for the same canva in the Terminate() part of the MyHitSelector file, the ps file is built [color=#008000](see part in green)[/color]

Could you give me an explanation ?

Many thanks,

Thomas

Hi Thomas,

Which version of ROOT, which platform, which compiler?

Cheers, Bertrand.

Hi Thomas,

Well, I cannot reproduce the problem win ROOT v5.34.18 on SLC6 64 bit with gcc 4.8…

Cheers, Bertrand.

Maybe this is more a PROOF-related problem. I can anyway print the canvas by using the Print function in the derived TSelector macro …

I work on Ubuntu 12.04 platform.

Hi Thomas,

Is it happening only within PROOF?

Cheers, Bertrand.
