Pointer access error #24
Description
The sweeping functions fail occasionally by producing following errors:
OSError: exception: access violation writing 0x0000000000000000
OSError: exception: access violation writing 0x000001DBB05E5000
OSError: exception: access violation reading 0xFFFFFFFFFFFFFFFF
This might be an error to Python's garbage collection and requires a strong python ref of the memory. Or needs to be allocated and resized for each run in python, similar to antenna output.
