From a recent build:

        $ build/run/tshark -G fieldcount
        There are 215003 header fields registered, of which:
                0 are deregistered
                2533 are protocols
                16078 have the same name as another field

        215000 fields were pre-allocated.
        * * Please increase PROTO_PRE_ALLOC_HF_FIELDS_MEM (in epan/proto.c)! * *

        The header field table consumes 1687 KiB of memory.
        The fields themselves consume 15117 KiB of memory.
        $ echo $?
        1

I boosted the #define in question to 220000 in

and it now works.
