397214 - Loading CMYK JPEG causes 100% CPU, then hangs browser

Status: RESOLVED DUPLICATE of bug 396031

(Core :: Graphics: ImageLib, defect)

Description

[Justin Dolske [:Dolske]]

With gfx.color_management.enabled set to |true|, I tried to load http://www.nps.gov/carto/RELIEFS/PINNrelief1_c.jpg ("May 2006 full resolution final color shaded relief file 3.1MB" via http://home.nps.gov/applications/hafe/hfc/carto-detail.cfm?Alpha=PINN

The browser pegged the CPU while loading and was nearly non-responsive (it's a giant image, but still...). After loading, the browser stopped responding entirely and I got the beachball of death.

[Note that the image won't render at all without CMS enabled. With CMS, the image renders incorrectly -- wonky colors, background is black instead of white -- but it looks like the patch in 44781 might address that.]

Note that Safari loads the page within a few seconds, and the fans on my MacBook never even spin up [with Minefield, they're in hurricane mode by the time the image has rendered].

Oh, forgot to note the build I was using: Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.9a8pre) Gecko/2007092004 Minefield/3.0a8pre

With the patch from bug 396031, the jpeg loads fine with black/white interpreted correctly.

With CMS disabled, see bug 44781 for the CMYK processing.
