If I understand it correctly, the hash value differs depending on the kernel configuration when the python binary is built, leading to different pickle objects which cannot be shared, making them incompatible .  I think the safest thing would be to remove the hash make the selection of the hash method unconditional, and to make this hash function working for all cases.
