Version
v20.10.0
Platform
Linux acfbcf435a24 6.7.4-200.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Mon Feb 5 22:21:14 UTC 2024 x86_64 GNU/Linux
Subsystem
Intl
What steps will reproduce the bug?
- Obtain a nodejs build compiled with
--with-intl=small-icu.* - Execute
new Intl.Segmenter().segment()in the REPL.
*In my case that was the nodejs package from Fedora 39 without nodejs-full-i18n. This can be obtained as follows:
- Create a docker/podman container with Fedora 39:
podman run --rm -it fedora:39 dnf install -y --setopt=install_weak_deps=False nodejs
How often does it reproduce? Is there a required condition?
Always, as long as no runtime ICU data is present.
What is the expected behavior? Why is that the expected behavior?
NodeJS should fallback to a locale-unaware string separator, not provide Intl.Segmenter at all, or raise a JS exception.
The status quo offers no possibility to know if segmentation is safe and calling it results in a segmentation fault and therefore instant termination of the process.
What do you see instead?
A segmentation fault
