Dear Jinsoo,
thank you for reporting.

Are you also getting the error in a GW calculation ?

The blacs and scalapack option in the configure were removed because they are not yet fully implemented.
I do not think the error is related to that. They were not in the 4.0.2 neither.

I've been finally able to reproduce the problem.
I did a quick workaround fix.

Can you try revision 105 and tell me if it works ?

Best,
Davide
