Segmentation faults #590

Closed khaxan closed 1 week ago

khaxan commented 1 year ago

I get a segmentation fault when running the following CSS from a third-party site. It happens with the CLI as well as the npm package. I have noticed the same issue with other CSS as well.

Seems to work on the playground. What version/config/settings are you using?
