Dear MadGraph developers,

we are trying to build MadGraph5 version 3.0.0.beta, and the `.compile.py` script fails:

Dear developers,

ATLAS generators team is waiting for resolution of this bug to begin testing this new version. Do you have any updates on this issue?

Hi Ivan, sorry for the late response. I did not aware of it (there were two reports related but I only replied the first one and forgot this one. Sorry.) What is the version of your gcc ? Also, what do you get when you compile IREGI manually in vendor/iregi/src by make ? Cheers, Hua-Sheng
