• hayro-jbig2: a symbol dictionary can loop over billions of empty height classes (25 s for a 10 KB stream)

• hayro-interpret: images with 1, 2 or 4 bits per component are unpacked to their declared size, so one byte of data costs memory in proportion to /Width × /Height

• hayro-interpret: B/b under transparency composites the stroke over its own fill

• hayro-syntax: the cycle check rejects a reference back to an ancestor, so resources shared with it are lost, and through the font cache depend on page order

• hayro-syntax: Array::iter::<T>() ends at the first entry that is not a T, so one dangling reference in /Annots or /Contents drops every entry after it
