             Bug #: 12987
           Summary: All compilations fail with void
                    llvm::ValueHandleBase::AddToExistingUseList(llvm::Valu
                    eHandleBase**): Assertion `VP.getPointer() ==
                    Next->VP.getPointer() && "Added to wrong list?"'
                    failed
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: enhancement

    Classification: Unclassified


All compilations fail on my box (Westmere + SUSE11 SP1) when optimizations are
active.
A simple code sample like :


#include <iostream>
#include <map>

int main(int argc, char** argv)
{
  std::map<int, int> mymap;
  mymap[0] = 1;
  mymap[2] = 1;

  return 0;
}


makes clang crash:

clang-3.1:
/appli_RD/INNO_REPOSITORY/binaries/x86_64_rostand/src/llvm-3.1.src/lib/VMCore/Value.cpp:485:

Assertion `VP.getPointer() == Next->VP.getPointer() && "Added to wrong list?"'
