Serialized arrays are not compatible between 32 and 64 bit systems #1177

These size_type bytes sizes are different on 32 and 64 bit systems. So a serialized object saved with 64 bits cannot be properly loaded on a 32bit system.

Thanks for the report. I'll fix this. Note that this will take a while since I'm on holiday.
