(From update of attachment 44839)
This is incorrect. GlyphPageTreeNode instances must not outlive the FontData
instances that they reference. That’s why the trees are pruned when the
FontData are deleted. It is wrong to keep using the invalid GlyphPageTreeNodes.
To fix this bug, one must first understand whether the FontFallbackLists are
not getting invalidated as expected, and why.
