            Bug ID: 28949
           Summary: String streams do not handle flush-only overflow
                    correctly
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: stdio
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
  Target Milestone: ---

_IO_sstr_overflow (fp, EOF) and _IO_wstr_overflow (fp, WEOF) always return EOF
and WEOF, even if the call was successful. This means that the caller has no
way of checking for failure.

    stdio-common: Add tst-memstream-string for open_memstream overflow

    This code path is exercised indirectly by some of the DNS stub
    resolver tests, via their own use of xopen_memstream for constructing
    strings describing result data.  The relative lack of test suite
    coverage became apparent when these tests starting failing after a
    printf changes uncovered bug 28949.
