Après une sortie de xcas non sollicitée, je n'arrive plus à recharger le fichier sur lequel je travaillais, lorsque je tente de le recharger xcas s'arrête avec le message
Le fichier euler.xws est ci-dessous. Quelques caractères douteux, par exemple -A (lignes 6 et 7), ne sont pas visibles lorsque j'édite le fichier avec emacs*** segmentation fault: bug in PARI or calling program.
