Extended Description

The following error shows up after running my program that is linked to my custom library that is made in a fashion described in the Summary.

test1: /usr/src/packages/BUILD/llvm-2.3/include/llvm/Support/CommandLine.h:477: void llvm::cl::parser::addLiteralOption(const char*, const DT&, const char*) [with DT = const llvm::TargetMachineRegistryEntry*, DataType = const llvm::TargetMachineRegistryEntry*]: Assertion `findOption(Name) == Values.size() && "Option already exists!"' failed.

(Yes my LLVM packages are not the latest 2.4 but edwin on IRC confirmed with the latest - I suppose)
I attached a sample code that will produce the error. It requires CMake for building. Furthermore it has been suggested to also paste the building phase in case somebody can spot something wrong with it.

Furthermore, I have confirmed that removing either of two sets from linmking {"LLVMX86.o"} or {"LLVMJIT.o", "LLVMExecutionEngine.o"} disables the assertion fail. The conclusion is that they both have to overlap at some point and maybe they both initialize the cl::opt.

THis happens when you get a .o file linked into both the main application and the plugin.

[llvmbot]

Another possible way to get this is if you link with libLTO.so as well as with
static versions of some llvm files.
