I have arrived to a smaller workaround/fix:

diff --git a/Source/WebCore/rendering/TextDecorationPainter.cpp b/Source/WebCore/rendering/TextDecorationPainter.cpp

     } else
-        intermediateTuples = tuples;
+        intermediateTuples.swap(tuples);

     // Step 3: Output the space between the ranges, but only if the space warrants an underline.
     float previous = 0;

What do we think about this? ��
