svg/custom/use-multiple-on-nested-disallowed-font.html sometimes fails an assertion in StyleSelectorParentPusher

• Component: Tools / Tests
• Status: RESOLVED DUPLICATE

[Mario Sanchez Prada]

The mentioned layout test is occasionally failing in the GTK Debug bots.

See this dump from the buildbot logs:

 Feb 08 01:19	77916	failure	#19083	Failed 1 test case (<1%) had incorrect layout 2 test cases (<1%) crashed
 Feb 08 00:50	77915	success	#19082	Build successful
 Feb 07 23:53	77914	failure	#19081	Failed 1 test case (<1%) crashed 1 api tests failed

Changes in 77915 and 77916 seem to be unrelated, hence skipping the test in GTK while not fixing the problem.

The crash, as dumped in the output:

ASSERTION FAILED: m_pushedStyleSelector == m_parent->document()->styleSelector()
(../../../Source/WebCore/dom/Element.cpp:90 WebCore::StyleSelectorParentPusher::~StyleSelectorParentPusher())


Adding the author of the test to CC.

It just fails for GTK?

As I understand it, not many of the debug bots run tests, so it isn't so surprising.

I just ran it in the GTK debug bots (32 and 64 bits) and it was randomly failing there.

[Dirk Schulze]

I can confirm the problem on my Mac debug build.
