Commencez par test.test_capi.test_misc.Test_testinternalcapi.test_threadstate_set_stack_protection et examinez Modules/_testinternalcapi.c autour de la ligne 3045, où l’assertion Azure Windows échoue. Reproduisez le test indiqué dans l’environnement Azure et suivez les valeurs de limite de pile impliquées. Le travail est terminé lorsque le test passe de manière fiable sur Azure sans l’échec de l’assertion.
