I only really know the symptoms of the (possible) bug, no idea about the cause. I'll keep my description high level so others know the gist of the issue, happy to answer additional questions.

I get different results from my program when I use PackedArray *f = PackedArray_create(1, len); vs PackedArray *f = PackedArray_create(2, len);. The only line of code modifying the array is PackedArray_set(f, offset, 1); and as such the number of bits should not matter.
