Do we want to do this via the API? Something like:
```
(target, process, thread, bkpt) = lldbutil.run_to_source_breakpoint(self, "// break here", lldb.SBFileSpec("main.cpp"))
frame = thread.GetFrameAtIndex(0)
v = frame.FindVariable('void_empty_cstring')
self.assertEq(v.GetSummary(), '')
v = frame.FindVariable('empty_cstring')
self.assertEq(v.GetSummary(), '')
```
