To make this a valid ticket, please test current FFmpeg git head and provide the failing command line you tested together with the complete, uncut console output.
Your operating system or your shell likely limits the length of the command line, I don't think this can be fixed within FFmpeg.

Note: See TracTickets for help on using tickets.
