--- Comment #3 from Rafael Avila de Espindola <rafael at espindo dot la> --- I see now that the corresponding commit on trunk was 31011b9a94fed33170c009292e82558336d1c4d7 (r261146). At that revision, the test in this bug passes. There was a more recent regression on trunk on revision a9b768f8f4fd471e315623b23c4f9e83463bf92e (r270433).
