After further triage this is caused by a lack of handling for BIND_SPECIAL_DYLIB_SELF and related special library ordinals within any of the binding formats. These can allow symbols to be bound internally, which was not a case we accounted for previously.

This particular binary is more obviously broken in this case as this library uses BIND_SPECIAL_DYLIB_SELF to look up its own Objective-C classes in __objc_classlist, resulting in immediate failure of the Obj-C Parser.
