           Summary: duplicate symbol...
           Product: clang
           Version: trunk
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: Fons.Rademakers at cern.ch
                CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com

Created an attachment (id=4495)

Source file exhibiting the problem

To see this behaviour do:

$ g++ -c aap1.cxx    (file fails with assert using clang++, bug 6565)
$ clang++ -c aap2.cxx
$ clang++ -dynamiclib -single_module -undefined dynamic_lookup -g -m64 -o
aap.so aap1.o aap2.o -ldl
ld: duplicate symbol __ZTS12TMatrixTLazyIfE in aap2.o and aap1.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)

recompile aap2.cxx with g++ and the issue disappears.

Cheers, Fons.
