             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.

(Snip ends) 

I am trying to make a reduced test case.

The build error started in revision 181105

Also reproduced in revison 181838
