This code:

    template <int I>
    constexpr int some_int() {
      return I;
    }
    
    constexpr auto five = some_int<5>;
    
    int main() {
      return five();
    }

Makes our clang throw an assertion:

    Assertion failed: (!V->hasBrokenDebugInfo() && "Module contains invalid debug info"), function doFinalization, file /b/build/slave/mac_upload_clang/build/src/third_party/llvm/lib/IR/Verifier.cpp, line 4435.

When run like this:

    ~/src/chromium/src/third_party/llvm-build/Release+Asserts/bin/clang++ -gdwarf-2 -std=c++11 invalid_debug_info_test.cc

Attached is the error output and the two files it references.
