           Summary: Linking error: multiple definition of `non-virtual
                    thunk to ...'
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: silver24k@gmail.com


When compiling attached sources, I get:
$ g++ -O2 -c test0.cpp
$ g++ -O2 -c test1.cpp
$ g++ -o test.exe test0.o test1.o
test1.o:test1.cpp:(.text+0x0): multiple definition of `non-virtual thunk to
FooBase::Bar()'
test0.o:test0.cpp:(.text+0x0): first defined here
collect2: ld returned 1 exit status

Changing -O2 to -O0 or -O1 does not help.

Using built-in specs.
