            Bug ID: 114033
           Summary: Failure of test darwin-cfstring1.C
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

The test g++.dg/other/darwin-cfstring1.C fails on x86_64-apple-darwin23 for
-std=gnu++14 and later:

FAIL: g++.dg/other/darwin-cfstring1.C  -std=gnu++14 (test for excess errors)
FAIL: g++.dg/other/darwin-cfstring1.C  -std=gnu++17 (test for excess errors)
FAIL: g++.dg/other/darwin-cfstring1.C  -std=gnu++20 (test for excess errors)

But the same test passes with -std=gnu++98:

PASS: g++.dg/other/darwin-cfstring1.C  -std=gnu++98 (test for excess errors)


The excess errors that result in failure are:
