            Bug ID: 81514
           Summary: g++.dg/lookup/missing-std-include-2.C FAILs on Solaris
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org

  Target Milestone: ---
            Target: *-*-solaris2.*

The new g++.dg/lookup/missing-std-include-2.C testcase FAILs on Solaris:

FAIL: g++.dg/lookup/missing-std-include-2.C  -std=gnu++11  (test for warnings,
line 13)
FAIL: g++.dg/lookup/missing-std-include-2.C  -std=gnu++11  (test for warnings,
line 24)
FAIL: g++.dg/lookup/missing-std-include-2.C  -std=gnu++11  expected multiline
pattern lines 45-53 not found: "\\s*@@ -7,6 \\+7,8 @@.*\\n    directives\\)\\.

FAIL: g++.dg/lookup/missing-std-include-2.C  -std=gnu++11 (test for excess
errors)

(32 and 64-bit, sparc and x86).

The output for l.13 is

/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/lookup/missing-std-include-2.C:
In function 'void test()':
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/lookup/missing-std-include-2.C:13:8:
error: 'string' is not a member of 'std'
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/lookup/missing-std-include-2.C:13:8:
note: suggested alternative: 'sprintf'

while Linux has the expected

/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/lookup/missing-std-include-2.C:
In function 'void test()':
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/lookup/missing-std-include-2.C:13:8:

/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/lookup/missing-std-include-2.C:13:8:
note: 'std::string' is defined in header '<string>'; did you forget to
'#include <string>'?
