You mean you'd rather debug a segfault in C than an exception with a 
traceback and an error message that is spot on in Python?

You have an error in your program logic, and you'll eventually run into 
those no matter what language you choose.

If you are too frustrated to look into the actual problem at the moment you 
can change the following loop

by replacing the append() with the extend() method

results = []
for i in range (0, slice_size):
    results.extend(transfer(data_out))

for now.
