Bug: No response with numpy 1.26.4, python 3.12.3, nuitka 2.3rc5 and --standalone

[ShapingView]

Update: It seems to work with numpy 1.26.3 but not with 1.26.4

My Environment

Running python 3.12.3 on windows 11 23H2

• installed python from https://www.python.org/ftp/python/3.12.3/python-3.12.3-amd64.exe and created a virtual environment from it using python -m venv venv-312-test
• installed nuitka with python.exe -m pip install https://github.com/Nuitka/Nuitka/archive/develop.zip

Nuitka version (used with mingw64)

2.3rc5
Commercial: None
Python: 3.12.3 (tags/v3.12.3:f6650f9, Apr  9 2024, 14:05:25) [MSC v.1938 64 bit (AMD64)]

Script

Compiling this script (hw.py) does not work

import time
import numpy as np

def f(inp):
    print("Hello " + inp)

def main():
    time.sleep(np.random.uniform())
    f("nuitka!")


if __name__ == "__main__":
    main()

Version without numpy works

import time

def f(inp):
    print("Hello " + inp)

def main():
    time.sleep(.5)
    f("nuitka!")


if __name__ == "__main__":
    main()

Behavior

Running this script with python works fine, but after compilation with nutika it doesnt

> python .\hw.py  # works fine 
Hello nuitka!

Remark:

• I am also using --mingw64 because I currently can't install newer MSVC versions. Not sure if that is relevant for this issue
• Without --standalone it works

>  python.exe -m nuitka --mingw64 --standalone hw.py

Thanks for your help! I'm looking forward to your feedback

I just tried it, and it works fine with the current factory branch, at least. We also ran large parts of Nuitka-Watch against that and it should be good. There will be a pre-release of it soon too.

The bug I have fixed might be one that shows only in certain malloc situations, on every n-th run, maybe that is why you found another version to work.
