--- Comment #25 from Jürgen Reuter <juergen.reuter at desy dot de> --- This is the part from the test-suite.log for the 4 failures, they are all in one particular feature of our code, so I am pretty sure that this is only one remaining open issue: | Starting simulation for process 'nlo_4_p1' | Simulate: using integration grids from file 'nlo_4_p1.m1.vg' | Simulate: activating fixed-order NLO events | QCD alpha: using a running strong coupling Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
