            Bug ID: 65718
           Summary: g++.dg/lto/pr65276 FAILs
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: aldyh at gcc dot gnu.org
              Host: i386-pc-solaris2.11, sparc-sun-solaris2.11
            Target: i386-pc-solaris2.11, sparc-sun-solaris2.11
             Build: i386-pc-solaris2.11, sparc-sun-solaris2.11

The new g++.dg/lto/pr65276 FAILs on Solaris 11 when using Sun ld:

UNRESOLVED: g++.dg/lto/pr65276 cp_lto_pr65276_0.o-cp_lto_pr65276_1.o execute
-flto -O0 -std=c++11
FAIL: g++.dg/lto/pr65276 cp_lto_pr65276_0.o-cp_lto_pr65276_1.o link, -flto -O0
-std=c++11

The failure is 32-bit only, the 64-bit multilib is fine.  The log only contains
truncated linker output:

output is:
ld: warning: symbol 'vtable for std::runtime_error' has differing sizes:^M
        (file cp_lto_pr65276_1.o value=0x10; file
/var/gcc/regression/trunk/11-gcc/build/i386-pc-solaris2.11/.

Re-running the test manually gives the full output:

ld: warning: symbol 'vtable for std::runtime_error' has differing sizes:
        (file cp_lto_pr65276_1.o value=0x10; file
