PyCall.py2array errors on adjoint.

Reproduisez la conversion de pandas DataFrame montrée dans l’issue sous Windows et macOS, puis examinez src/pybuffer.jl:134 et src/conversions.jl:350,400,407,421, là où la stack trace entre dans PyCall. Comparez la conversion adjoint qui échoue avec les chemins de conversion associés. C’est terminé lorsque le reproducer ne plante plus et que la couverture de régression vérifie le comportement.
