Python ctranslate2 breaks with glibc 2.41: cannot enable executable stack

[igormp]

After upgrading to glibc==2.41, ctranslate2 now stopped working with Python 3.12.8.

After installing it and trying to import it, I'm met with the following:

import ctranslate2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/igor/.cache/pypoetry/virtualenvs/ctranslate-_DJS7Z3B-py3.12/lib/python3.12/site-packages/ctranslate2/__init__.py", line 21, in <module>
    from ctranslate2._ext import (
ImportError: libctranslate2-bc15bf3f.so.4.5.0: cannot enable executable stack as shared object requires: Invalid argument

Trying to clear the execstack flag leads to this other error:

$ execstack -c /home/igor/.local/lib/python3.12/site-packages/ctranslate2.libs/libctranslate2-bc15bf3f.so.4.5.0
execstack: /home/igor/.local/lib/python3.12/site-packages/ctranslate2.libs/libctranslate2-bc15bf3f.so.4.5.0: section file offsets not monotonically increasing

Maybe related to #1698

same with python 3.10, uv and glibc 2.41

I've got the same error with python 3.12.8, and also glibc 2.41(+r2+g0a7c7a2e283a-1).

This said, the stable (and Arch Electron) version(s) of Discord was hit with the exact error issue recently. It affected the voice chat component and made it so Discord couldn't access your mic info. I'm guessing the same dependency affected them both. That said, the AUR indicates that vanilla Discord doesn't use Python.

The only non-optional shared dependency I'm seeing between vanilla Discord and the Arch Electron version is libxss... which is downstream from glibc. I'm thinking maybe they need some info, if they don't have it already. 😅

Same here in Arch Linux with Python 3.12.8 and glibc 2.41+r2+g0a7c7a3e283a-1

ImportError: libctranslate2-bc15bf3f.so.4.5.0: cannot enable executable stack as shared object requires: Invalid argument

Downgrading to glibc-2.40-1 temporary addresses the issue:

pacman -U https://archive.archlinux.org/packages/g/glibc/glibc-2.40-1-x86_64.pkg.tar.zst \
https://archive.archlinux.org/packages/l/lib32-glibc/lib32-glibc-2.40-1-x86_64.pkg.tar.zst

same issue on arch with python 3.10 but downgrading solved it

Fwiw, another likely workaround would be to use patchelf instead of execstack:

patchelf --clear-execstack /home/igor/.local/lib/python3.12/site-packages/ctranslate2.libs/libctranslate2-bc15bf3f.so.4.5.0

Normally, downgrading such a package is not a good idea, as it may prevent your system from booting.

I attempted this, but the same error was returned upon running.

this works for me! Thank you. Make sure to replace user with your username (command whoami) if you have it installed globally, else replace /home/user/.local/lib/ with path_to_venv/lib/...
/home/user/.local/lib/python3.12/site-packages/ctranslate2.libs/libctranslate2-bc15bf3f.so.4.5.0

I believe my PR at #1852 is finally ready, which should fix this issue on Linux. Hopefully someone will find time to take a look at it.
