read_feather error with 32 GB file

arrow v.6.0.0.2 results in the following error when attempting read_feather on a 32 GB feather file:

Error: Invalid: Invalid read (offset = 7140512496, size = -956703880)

Start by reproducing read_feather on a 32 GB Feather file with Arrow v.6.0.0.2 and record whether the reported offset and negative size recur. Trace the read path that handles these values and verify the same file can be read successfully without the Invalid read error.
