> What do you think of using alloca() instead of an "PyObject *small_stack[5];" which has a fixed size? alloca() is not in POSIX.1. I afraid it would make CPython less portable. > Note: About your patch, try to avoid _PyObject_CallArg1() if you care of the usage of the C stack, see issue #28858. I don't understand how can I avoid it. > How do you check the stack consumption of PyObject_CallFunctionObjArgs()? Using a script from issue28858.
