Sorry I do not understand your reasoning; this patch does nothing, since __PYTHONOCC_MAXINT__ is defined as 2147483647 by environment.py. Anyway I tried your branch, and __hash__ overloading still segfaults :( Denis _______________________________________________ Pythonocc-users mailing list Pythonocc-users@gna.org https://mail.gna.org/listinfo/pythonocc-users
