Hi Rodrigo,

 

Argh, sorry. I was rushed earlier. The correct workaround is:

 

firedrake-update --petsc-int-type int32

I have reduced your code to a 5 line test case which exhibits the issue: https://github.com/firedrakeproject/firedrake/issues/1523 .

 

I think we have an assumption somewhere that long == int64_t.

 

Regards,

 

David

Hi, David.

 

Thanks for the feedback.

I think the 32bit indices are enough for the problem I'm trying to solve.

 

If you need more information about my test case, please let me know.

 

Regards

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.

 

Regards,

 

David

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.
