            Bug ID: 18442
           Summary: re_syntax_options namespace
           Product: glibc
           Version: 2.21
            Status: NEW
          Severity: normal
          Priority: P2
         Component: regex
          Assignee: unassigned at sourceware dot org
          Reporter: jsm28 at gcc dot gnu.org
                CC: drepper.fsp at gmail dot com
  Target Milestone: ---

Use of regcomp (POSIX) brings in references to re_syntax_options (non-POSIX);
re_comp (UNIX98 and older legacy) actually uses re_syntax_options (not in those
standards) rather than just being in the same .o file.  (As this is a data
symbol that users can set directly, fixing this is harder than simply using an
implementation-namespace name with a weak alias as can be done for functions.)

commit 9d12d7652b830635528639ece2206ecf5bb9ffbf
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Thu May 21 16:24:24 2015 +0000

    linknamespace: whitelist re_syntax_options.

    This patch adds re_syntax_options (bug 18442) to the set of symbols
    that are whitelisted in the linknamespace tests because, while the
    references to them are genuine bugs that should be fixed, the
    involvement of data symbols makes them harder to fix than most such
    bugs.

    Tested for x86_64 and x86.

        * conform/linknamespace.pl (@whitelist): Add re_syntax_options.
        * conform/Makefile (test-xfail-UNIX98/regex.h/linknamespace):
        Remove variable.
        (test-xfail-XOPEN2K/regex.h/linknamespace): Likewise.
        (test-xfail-POSIX2008/regex.h/linknamespace): Likewise.
        (test-xfail-XOPEN2K8/regex.h/linknamespace): Likewise.
