Comment 4 for bug 1400049

Hi Rikkert,
I don't know why now, if I try to launch the directory with p p > t t~ + 2j [NLO], a compilation Error occurs when trying to compile P2_gg_ttxuux directory! :(
Anyway... As suggested in your article (arXiv:1209.6215.v1 - Merging meets matching in MC@NLO), I limited top-anti top production to the case t t~ + 1j [NLO]. After compiling all the P* directories and after

, I get this error:

/afs/cern.ch/work/f/fgiuli/public/MG5_aMC_v2_2_2/ttbar_j_NLO/SubProcesses/P1_gg_ttxg/GF3: line 24: 12228 Segmentation fault (core dumped) ../madevent_mintMC > log.txt < input_app.txt 2>&1

Then, as you suggested me previously, I went to /afs/cern.ch/work/f/fgiuli/public/MG5_aMC_v2_2_2/ttbar_j_NLO/SubProcesses/P1_gg_ttxg/ and I execute '../madevent_mintMC <input_app.txt'.
I have obtained:

 ---- POLES CANCELLED ----
../madevent_mintMC <input_app.txt ERROR, NaN found for dsigS, setting dsigS to 0 for this event
 ERROR, NaN found for dsigS, setting dsigS to 0 for this event

and then the program stucked.
What have I to do?

Cheers,
Francesco
