Created attachment 430210 [details] Backtrace Running the test in a debug build of the GTK minibrowser, there is an assertion tripped: STDERR: ASSERTION FAILED: measuredWidth >= 0 STDERR: ../../Source/WebCore/rendering/ComplexLineLayout.cpp(536) : void WebCore::setLogicalWidthForTextRun(WebCore::RootInlineBox*, WebCore::BidiRun*, WebCore::RenderText&, float, const WebCore::LineInfo&, WebCore::GlyphOverflowAndFallbackFontsMap&, WebCore::VerticalPositionCache&, WebCore::WordMeasurements&) This test was added in bug221628 and intentionally creates a NaN by combining a very large zoom with a letter-spacing of zero. The bugfix fixed this issue for other platforms by replacing a NaN with 0 in certain places but this is apparently not sufficient for GTK.
