Do you have 1TB or more in this file system?  If so, then this is
(unfortunately) the expected result.  statfs() has int32_t structure
members, which overflow if you have 2^31 blocks or more in your file
system.  2^31 blocks is 1TB.

At a guess, smaller file systems.  Just a guess, though.  EOVERFLOW
basically says that the result doesn't fit in the data structure
available.  Rather than return a wrong answer, it returns no answer.
