[issue41335] free(): invalid pointer in list_ass_item() in Python 3.7.3

[Howard A. Landman]

Getting closer to isolating this. A small program that does nothing but call read_regs24() over and over dies with the same error after about 107.4M iterations. So it seems to be definitely in that method. But that only takes a few hours, not half a day. Going to try to separate the SPI operation from the remaining Python code next.
