There were two problems: 1. parse_compressed_object_with_index() parses indirect objects without going through Parser::parse_indirect_value(), so push_reference() / pop_reference() weren't called. Manually call them, both for the indirect object containing the object stream and for the indirect object within the object stream. 2. The indirect object within the object stream got decrypted twice: Once when the object stream data itself got decrypted, and then incorrectly a second time when the object data within the stream was read. To fix, disable encryption while parsing object stream data (since it's already decrypted). The test is from http://opf-labs.org/format-corpus/pdfCabinetOfHorrors/ which according to readme.md at the same location is CC0.
