<div>Hi Lisandro,</div>
<div><br>
</div>
<div>Yes, that is the case, I ended up installing following your instructions since it was the simplest way to do it. I was actually trying to install PETSc 3.11 and then to install petsc4py using pip and providing environmental variables for PETSC_DIR
and PETSC_ARCH, but I couldn’t make it work. Later Lisandro pointed out I could not use Python 3.8 for this.</div>
<div><br>
</div>
<div>Best,</div>

<div>It looks like you have an inconsistent build, or a memory overwrite. Since you are in Python, I suspect the former. Can you build</div>
<div>PETSc from scratch and try this? Does it work in serial? Can you send a small code that reproduces this?</div>

<div>Well, I think Alejandro installed PETSc/petsc4py via pip as per my instructions. Can you confirm, Alejandro?</div>
