This is a duplicate of bug 271903. It is similar to bug 268770, but with a RenderInline ruby split into multiple continuations because of forced line breaks caused by block descendants. RELEASE_ASSERT(!m_previous) fails in WebCore::RenderObject::destroy, with a misparented m_previous. It was badly attached in RenderTreeBuilder::Ruby::attachForStyleBasedRuby with the following bad configuration:

This is happening when creating a renderer for the RT element, here is the DOM tree:


BODY	0x7f363e001230 (renderer 0x7f363e0017f0) 
	#text	0x7f363e0045c0 "\n\n"
	RUBY	0x7f363e004620 (renderer 0x7f363e005d20) 
		#text	0x7f363e004700 "\n"
		RT	0x7f363e004820 (renderer (nil))  CLASS=class1
			#text	0x7f363e004760 "\n"
			TIME	0x7f363e004900 (renderer 0x7f363e006b30)
