Have you compiled atom.F with high optimizations?

If so, try and compile with -O1?

How do compiled with high optimization? I am New

We try but I have the same error

Nick Papior (nickpapior) said : #4

Note, if they are only signalled and without errors then there should be nothing wrong, i.e. your psf should be fine.

PS. I said, do NOT compile with high optimizations.
PPS. I suggest you talk to your local computer administrator about these things. He/she should know.

I still have the same problem, but it only happens to me for the Te, try with Cu and V, and with put xc = psr it was solved

Can you help with this problem?
