Thank you for your quick reply. Yes, as I wrote above there are ways around it by creating a stable in-memory representation and comparing that to a stable in-memory representation of the expected output. Since both input are several hundred megabytes in size, this would be CPU intensive but do-able. I would've just likeld to avoid treating this output in a special way because I also compare other files and it is most easy to just md5sum all of the files in one fell swoop. I started using PYTHONHASHSEED to gain stable output for a certain platform/version combination. When I uploaded my package to Debian and it was built on 13 different architectures I noticed the descrepancy when the same version but different platforms are involved. From my perspective it would be nice to just be able to set PYTHONHASH32BIT (or whatever) and call it a day. But of course it is your choice whether you would allow such a "hack" or not. Would your decision be more favorable if you received a patch implementing this feature?
