Preprocessed source file to reproduce the error.
The CallAndMessageChecker might get into infinite loop at
'generateVisitorsDiagnostics' function in 'BugReporter.cpp' due to a loop in
the errorNode graph.
I have attached a demo code that could reproduce this error. You could
reproduce the error by running clang static analyzer on the code with
'core.CallAndMessage' checker. I am unsure what causes errorNode graph to
contain a loop. Might be the function that passes right-value reference?</pre>
