           Summary: Using clang++ as linker does not feed symbols to
                    c++filt...
           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

cint/cint/src/dict/gcc4strm.o cint/cint/src/dict/longif3.o -lm
-Wl,-rpath, at loader_path/../lib   -ldl

gives:

Undefined symbols:
  "__ZTV12G__srcreaderI10G__fstreamE", referenced from:
      __ZN12G__srcreaderI10G__fstreamEC2Ev in bc_cfunc.o
ld: symbol(s) not found
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The same with g++ gives:

Undefined symbols:
  "vtable for G__srcreader<G__fstream>", referenced from:
      G__srcreader<G__fstream>::G__srcreader()in bc_cfunc.o
ld: symbol(s) not found
collect2: ld returned 1 exit status

Notice clang++ uses:

/usr/libexec/gcc/i686-apple-darwin10/4.2.1/ld

while g++ uses:

/usr/libexec/gcc/i686-apple-darwin10/4.2.1/collect2 


Cheers, Fons.
