Discussion:
strstream::rdbuf
has the same issue with a missing const_cast
on &sb
.
istrstream::rdbuf
and ostrstream::rdbuf
got this right,
but each with a different style (see issue 252).

Proposed resolution:
This wording is relative to N4750.
Change 99 [depr.strstream.oper] p1 as indicated:
strstreambuf* rdbuf() const;-1- Returns:
const_cast<strstreambuf*>(&sb)
.
