I confirm this bug. If you can live with 32bit PETSc integers then a workaround is:

firedrake-update --petsc-int-type int64

Otherwise, I will try to get to the bottom of the issue.

Dear Rodrigo,

Thanks for this bug report. It looks like the interpolation code is not safe for the PETSc int64 case. I will look further.

Regards,

David

Hello,

I'm trying to evaluate a Function at a point, but I get the error bellow. Could anybody help me on that?

The log files are attached.
