What steps will reproduce the bug?

I do not know how to reproduce without installing third-party dependencies. On aarch64, ppc64le, and s390x Fedora Rawhide builders (but NOT x86_64), these steps always lead to a segfault:

• Install jupyterlab (with sudo dnf install jupyterlab on Fedora)
• wget https://github.com/mwouts/jupytext/archive/v1.16.1/jupytext-1.16.1.tar.gz
• tar xf jupytext-1.16.1.tar.gz
• cd jupytext-1.16.1/jupyterlab
• jlpm install

How often does it reproduce? Is there a required condition?

Those steps lead to a segfault every time on the 3 architectures indicated.

What is the expected behavior? Why is that the expected behavior?

Packages should be installed instead of segfaulting.

What do you see instead?

Additional information

This looks very similar to https://github.com/nodejs/node/issues/45283.

Correction: this crash only happens on aarch64. Failures on other architectures turned out to have different causes.

Also, by default the Fedora builders operate in an ASCII environment; i.e., LC_ALL=C. I discovered today that changing the environment to C.UTF-8 makes the segfault stop happening. If a Unicode environment is required, then a failure is okay, but it should be a failure with a message indicating the problem, not a segfault.

Suspect this is similar to/related to https://github.com/nodejs/node/issues/51752.

For those coming here and seeing this on Fedora: we determined in the Fedora bug that the problem can at least be worked around by installing the nodejs-full-i18n package.

It's definitely the same issue as #51752 .
