Traceback (most recent call last):

OSError: [Errno 0] Error

I am absolutely sure that this problem is related to `qemu-aarch64`, because the same python build works perfectly in aarch64 machine. In addition, python for arm architecture with `qemu-arm` does not have such a problem."""
reproduce = """Note, this instruction specifies the stage of installation of that very python. But since it is compiled for Termux, you will have to use some scripts.
1. Create a simple codespace environment.
2. Run the following commands through the terminal:
```
git clone https://github.com/termux-pacman/glibc-packages
cd glibc-packages
./get-build-package.sh
sudo mkdir /data
sudo chown codespace /data
sudo chgrp codespace /data
sudo apt update
sudo apt install patchelf
./scripts/setup-cgct.sh
```
3. Run the following command. Note that the installation phase will start there. You should stop the script when the installation phase is complete.
```
./build-package.sh -I -w --library glibc gpkg/gobject-introspection
```
4. Install standard qemu via apt.
5. Run the following command:
```
qemu-aarch64 /data/data/com.termux/files/usr/glibc/bin/python3.12 -c "import time; time.time()"
```"""
additional = """- For some reason this error only occurs in the environment from GitHub. On my computer this error does not occur.
 - Here is a log of one of the github actions, which shows an attempt to compile packages with python on different architectures - https://github.com/termux-pacman/glibc-packages/actions/runs/11023254502.  
For reference, I use qemu for more flexible compilation of packages. And in github actions, qemu is installed here - https://github.com/termux-pacman/glibc-packages/blob/main/.github/workflows/build.yml#L35."""
