Crash when reweighting at NLO
Hello,
I had several crashes when trying to do some reweighting at NLO. I am now using MadGraph 3.1.0, but the same crash was happening for earlier versions.
For a minimal example I am using the default SM model for a p p > e+ e- [QCD] process and then in the reweighting card I have added
change mode NLO
launch
set mass 6:[100,150,200]
as in the online example. The generation of the events looks fine but when the reweighting process start it seems like there are some compilation problems and we can't figure out what is causing it.
Here is the debug log of this failed run. Please tell me if you need more information about the machine that we are running Madgraph with.
Thank you.
