Thanks.

The program size is 404574, which is greater than the limit of 9999, so approximately all of the wall time must be due to compilation. I guess I need to restrict the use of `.' as well. :(

Thanks for the fix! Uploaded the roll as https://chromium-review.googlesource.com/c/chromium/src/+/1235336
