All new files my old `btrfs` filesystem creates are above 32-bit inode space:
$ touch a && stat '-c%i' a
11833717710
Very occasionally I build 32-bit `i686-linux` packages. Sometimes they fail to run against file with so large inodes.
Two casualties today:
- `doxygen`: https://github.com/doxygen/doxygen/pull/11518
- `graphviz`: https://gitlab.com/graphviz/graphviz/-/merge_requests/4269
