What happened with this?

There is no way that CL is involved; if you look at it, it deletes a single line, which is an obsolete TODO comment.

It looks like the crash under clusterfuzz is because ICU returned something unexpected - is that an artifact of the clusterfuzz environment? Does it have a proper ICU configured?
