It depends on the system configuration.  For some file systems, inode
numbers outside the 32-bit range can be quite common.  This impacts
32-bit applications even if they never use ino_t because functions such
as fstat and readdir cannot know that these fields are unused.

We've been working around this for our 32-bit builders with special file
system configuration because like many, we do not build everything with
-D_FILE_OFFSET_BITS=3D64.
