The Bugbug bot thinks this bug should belong to the 'Core::JavaScript Engine' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Without the ability to test this we'll have a very difficult time making progress. Is it possible to generate a reduced test case?

This is surprising. In the past we used to be the browser which had the most stack space available, except when generators were on the stack.
Could it be that generators are filling up the stack space?
