I expect that this issue is obsolete in the 2nd decade of the 21st century (sorry for the pun). If it isn't the case and it's still important to you, feel free to re-open the issue on https://github.com/rdiff-backup/rdiff-backup/issues

In tests rdiff-backup does on source and target directories it should also check whether Python lstat function returns 64 bit or 32 bit (signed!) values for file sizes.

The problem is that if Python on a target system has been compiled without large file support backup of > 2 GB files always fail with "Updated mirror temp file does not match source" as source and target file sizes differ (because of an integer overflow).

I believe rdiff-backup should detect this in advance and at least issue a meaningful warning because it is hard to understand what is the problem from "Updated mirror temp file does not match source" message in this case. (And maybe skip backuping > 2 GB files altogether.)
