Hi Vincent,

I really struggle to understand what’s happen, I have made 50 student to run this tutorial yesterday on various linux configuration and it was working for all of them.
What is really surprising is that your error should be critical enough to occur on all system.
The only reason that I can think about is that you have a bugged version of gfortran, but at the same time this seems very unlikely.

So I’m really on the dark here.

Sorry,

Olivier

Hi Olivier,

Perhaps I wasn’t giving enough details.

I initially have madgraph 2.2.3 installed a year ago. Then, recently I realized that there’s an upgrade, so I removed it and installed madgraph 2.3.3.
The error I reported happened when I try to use madgraph 2.3.3. I am wondering if I am not doing the upgrade properly.
Now, I have switched back to madgraph 2.2.3 and things are working. And I am happy with madgraph 2.2.3 at the moment, so there is no rush to get to 2.3.3. Still it will be nice to know if I have made any mistake.
Please let me know if this rings a bell, or if there’s anything else I can provide to help understand the problem.

Thanks&Regards,
Vincent

Hi Vincent,

I have run it once more time and check the line that was reported in your case.
It seems that your file maxamps.inc has a correct value which creates the crash.

I test it again today at another school (~25 peoples) and no problem reported...

I will close the bug but I have no idea what problem you face.

Sorry,

Olivier
