Crash during p p > a [QCD]

Hello,

Sorry for the multiple questions.

I'm trying to do the process p p > a [QCD], and it crashes with the following output.

INFO:

I'm using gcc 4.7.2, and did "make clean && make" in the ./vendor/CutTool/ because of other problem (Question #250594). I installed MadGraph again and didn't change any other setting.

Thank you.
