For what it's worth, the library has been that way since June 28, 2001:

http://cvs.haskell.org/cgi-bin/cvsweb.cgi/fptools/libraries/base/Foreign/
Storable.hs?rev=1.1&content-type=text/x-cvsweb-markup

http://cvs.haskell.org/cgi-bin/cvsweb.cgi/fptools/libraries/base/GHC/
Storable.lhs?rev=1.1&content-type=text/x-cvsweb-markup

This seems to be copied from Marcin's QForeign which had the same type from 
Jan 2, 2001 - March 18, 2001 (i.e., the entire lifetime of the library)

http://cvs.sourceforge.net/viewcvs.py/qforeign/qforeign/lib/
QStorable.hsc?rev=1.7&view=markup

On this evidence, it looks like it's an error in the report.

The type is certainly consistent with the type of plusPtr if you
think about implementing peekByteOff like this:

  peekByteOff p o = peek (plusPtr p o)

And, since peekByteOff is primarily for use when peekElemOff doesn't work 
(i.e., for structs), it makes sense to change the type.
