Dear Madgraph experts, We are studying the following process p p > j j w+ [QCD] using the loop_sm model and the zero_mass_ckm restriction file on MG5_v3_4_0. After launching madevent, a segmentation fault seems to arise from the interface between aMC@NLO and Fixed order such that all jobs crash. ./ajob1 : line 38 : 1355624 Segmentation fault ../madevent_mintFO > log.txt < input_app.txt 2>&1 The error looks a bit similar to the question #675872 but I do not use an external version of FastJet and the jets have non-zero minimum pT. What is the issue here ? Thank you in advance.
