Status: RESOLVED DUPLICATE of bug 844819

(Core :: Graphics, defect)

Description

Attachment: test.html

The following style causes a crash in Aurora 26.0a2 and Nightly 27.01. This is not a problem in Release 24.

The problem is with including background-size.

<style>
    body
        {
          background-image:url('fox.jpg');
          background-color:#cccccc;
          background-size:100% 100%;
        }
</style>

image used for poc - shouldn't be related to the problem, but an image is needed for the crash to happen.

Hmm.  I don't see a crash here, on Mac.  In a debug build I do see:

WARNING: Surface size too large (exceeds CoreGraphics limit)!: file ../../../mozilla/gfx/thebes/gfxASurface.cpp, line 373

Michael, do you have a breakpad incident for the crash you see?

That sure looks like bug 844819, but that's reported on Windows.

I wonder whether we're managing to OOM in the graphics code somewhere here or something.

bug 844819 includes mac crashes, too (bug 844819#c8 and duped bug 922806).
