C++ reproducer
This assertion was found when trying to compile DAGCombiner.cpp from the
llvm-8.0 release using clang from today's trunk (r365881).
When compiling the attached program using:
$ clang -fsanitize=address -std=c++11 -fno-exceptions -fno-rtti -g -O2 f.cpp
you get the following assertion:
clang-9:
/home/edasten/upstream/monorepo/llvm/lib/CodeGen/LiveDebugValues.cpp:331: bool
{anonymous}::LiveDebugValues::OpenRangesSet::empty() const: Assertion
`Vars.empty() == VarLocs.empty() && "open ranges are inconsistent"' failed.
The program has been reduced with a run of creduce, but it is still a bit
messy, and can probably be made smaller.</pre>
