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 ________________________________ De : firedrake-bounces@imperial.ac.uk <firedrake-bounces@imperial.ac.uk> de la part de Lawrence Mitchell <lawrence.mitchell@imperial.ac.uk> Envoyé : jeudi 8 février 2018 11:27 À : firedrake@imperial.ac.uk Objet : Re: [firedrake] .at() PETSC error On 08/02/18 11:17, Floriane Gidel [RPG] wrote:
Hi Lawrence,
Thanks for the guidance. You'll find the output attached.
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.
