gfortran compilation Error in MadGraph event generation

This is related to using an old version of mg5amc with a recent ccompiler.

To use old version of MG5sMC you also need to use old version of the compiler.

Using one of our official version (either the LTS 2.9.6 or our latest feature version 3.3.0) would solve your issue

Cheers,

Olivier
