OK, I grabbed the pt/easy-script-2 branch (commit 4c69fd388e17), and
see build failures for a 'make -C perf' build using gcc version 7.3.0
(Ubuntu 18.04):

builtin-script.c: In function ‘parse_output_fields’:
builtin-script.c:2571:22: error: array subscript is above array bounds [-Werror=array-bounds]
output[j].fields &= ~all_output_options[i].field;

itrace_synth_opts

Thanks,

p.s. FWIW, my make VF=1 output:
