            Bug ID: 62022
           Summary: [4.10 regression] 27_io/basic_ofstream/pthread2.cc
                    FAILs
           Product: gcc
           Version: 4.10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
              Host: *-*-solaris2.1[01]
            Target: *-*-solaris2.1[01]
             Build: *-*-solaris2.1[01]

Between 20140725 (r213049) and 20140801 (r213453),
27_io/basic_ofstream/pthread2.cc started to FAIL on Solaris:

FAIL: 27_io/basic_ofstream/pthread2.cc execution test

(both 32 and 64-bit, sparc and x86, Solaris 10 and 11):

Program received signal SIGSEGV, Segmentation fault.

#7  0xfe516cf0 in ?? () from /lib/libc.so.1
#8  0x00000000 in ?? ()

Only happens with current libstdc++.so, ok with 4.8 one provided by vendor.
