PyCall.py2array errors on adjoint.

Reproduzieren Sie die im Issue gezeigte pandas DataFrame-Konvertierung unter Windows und macOS und untersuchen Sie anschließend src/pybuffer.jl:134 sowie src/conversions.jl:350,400,407,421, wo der Stacktrace in PyCall eintritt. Vergleichen Sie die fehlschlagende adjoint-Konvertierung mit verwandten Konvertierungspfaden. Als erledigt gilt die Aufgabe, wenn der Reproducer nicht mehr abstürzt und die Regressionstestabdeckung das Verhalten verifiziert.
