A syntactically valid pcapng file containing many repeated packet-comment options can abort TShark when it builds the full protocol tree with -V. Wireshark renders every comment before entering the frame dissector's exception boundary. The normal one-million-tree-item safeguard consequently raises an uncaught DissectorError, terminating the process instead of reporting a bounded per-packet dissection error.
The Frame protocol metadissector could crash.
