Yes, in the original problem there were multiple taps. Nonetheless this code produces the same error. The main reason is because any tap that is different from -1 produces a mit_sot sequence and not a sit_sot sequence. The idea was that sit_sot sequences are those where you reuse the last output and you do not need any index computation to figure out the previous output.

I've tried to run this code without the fix for the save_mem optimization and get an error, and run it with the optimization and get no error.
