Fri 16 Oct 2015 07:54:04 PM UTC, comment #2: One option for what I think what may be wanted for the fuzzer is to put an 'ifndef TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES' around the current define of TT_CONFIG_OPTION_MAX_RUNNABLE_OPCODES, so that it can be changed without actually changing ftoption.h .
