             Bug #: 51361
           Summary: [4.7 Regression] 471.omnetpp of SPEC2006 fails to
                    build with -fprofile-generate
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: gcov-profile
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: venkataramanan.kumar.gnu@gmail.com


When we build SPEC2006 benchmark omnetpp with  -fprofile-generate, it fails
with lot of undefined references to instrumented sysmbols.

I am trying to make a reduced test case.

Probably a duplicate of Bug 51113.
Nathan is still working on a partial revert of his commit.

This could also be related to PR 51449.

I don't think it is -- that defect relates to __gcov0__FOO objects, this one
mentions the __gcov__FOO objects.  Also, that defect was apparently introduced
by an even more recent cleanup patch.
