It crashed both for me and the person next to me, so I assumed that it was pretty universal. I probably should have given more details:

Comment 3

[Adam Guthrie]

There are plenty of bugs on this. Basically, XFT/X11 dies when we try to render huge fonts.

Comment 4

[Adam Guthrie]

Attachment: gdb stacktrace using --sync

Comment 5

[Adam Langley]

Only just noticed the two layers of font-size: 20em - I only intended one.

Sorry about that. Seraches for crash and huge font don't seem to turn up anything useful. If you have a good bug number to make this a dup of, please do.
