[issue46600] Python built with clang -O0 allocates 10x more stack memory than clang -O3 on a Python function call

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

stack_overflow-4.py: Update script from bpo-30866 to measure stack memory usage before Python crash or raises a RecursionError.

I had to modify the script since calling a Python function from a Python function no longer allocates (additional) memory on the stack! See bpo-45256 "Remove the usage of the C stack in Python to Python calls".
