Hi Lawrence,

with

$ firedrake-clean
$ export PYOP2_DEBUG=1
$ gdb --args python TOC2.py

(gdb) break PetsError

(gdb) run

I have no error anymore. So it seems that it fixed the issue! Should I try to run it with

$ python TOC2.py

to make sure that it's fixed ? What was the issue then?

Thanks,

Floriane

OK, that, unfortunately, was not very enlightening.

We see that the segfault happens in auto-generated code, but can't see
the problems.

Let's try running the compiled code in debug mode.

Do:

$ firedrake-clean
$ export PYOP2_DEBUG=1
$ gdb --args python TOC2.py

And follow the instructions as before.

Thanks,

Lawrence
