two .cpp files and a .sh script to reproduce
If we compile one module with -g and another with -gmlt this can trigger
a crash in DwarfDebug.
llc:
/home/probinson/projects/llvm-org/trunk/llvm/lib/CodeGen/AsmPrinter/DwarfDebug.cpp:1216:
virtual void llvm::DwarfDebug::endFunction(const llvm::MachineFunction*):
Assertion `DbgValues.empty()' failed.
It looks like this assert was added in r218129.
Also another one next to it, for AbstractVariables.empty().
We should be able to conjure up repro for that one too if you want.</pre>
