Bug 108608 – [Qt] ASSERT(!brush.transform().isRotating()) in GraphicsContextQt

• Status: RESOLVED
• Resolution: WONTFIX
• Component: SVG

[Renata Hodovan]

Assertion faulire was found during SVG fuzzing:

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff57c13b5 in WebCore::drawRepeatPattern (p=0x7fffffffbc40, pattern=..., rect=...)
    at /home/reni/repos/webkit2/Source/WebCore/platform/graphics/qt/GraphicsContextQt.cpp:679
679	    ASSERT(!brush.transform().isRotating());


The test was:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
	<pattern id="dummyPattern" width="100" height="100" patternTransform="skewX(45)">
	</pattern>
	<rect x="0" y="0" width="50" height="30" fill="url(#dummyPattern)"></rect>
</svg>

Important note: if you move the </pattern> closing tag to the end of the previous line then everything is OK. O_o

It was a Qt specific issue, so it can be closed now.
