Comment 4 Michael Catanzaro 2023-05-26 17:52:54 UTC
This fix contains a test case, so for we can verify that the fix actually works. I've attached it to this bug. You can run:

$ /usr/libexec/webkit2gtk-4.0/jsc test.js

Without the fix, the test case uses lots of memory and keeps running indefinitely. With the fix, it should stop right away.
