You are using BASE_NONE for integers. This isn't allowed. Ref: doc/README.developer.
BTW, any reason why one of your display filters is called "mac.priority" and not "abc.priority"?

I fixed the change you mentioned and am still failing at the same proto_register_field_array call.

should be
{ &hf_abc_txPower,
{ "txPower", "abc.txPower",
FT_UINT8, BASE_DEC, NULL, 0x0,
"Transmit power for message in dBm", HFILL }
},
Stepping through the code (eg: proto_register-field_array) is the way to
find bugs like this.
