--- Comment #2 from Tom Honermann <tom at honermann dot net> ---
(In reply to Tom Honermann from comment #1)
Actually, the test case in comment 1 seems to be a different issue; its failure
is a regression introduced in r234231 via bug 70095.
As of r234231 (and up through at least r234502), the test case in comment 0
triggers an ICE.
