Diagnostic: Multithreading issues.
Rationale : All reported problems can only occur if accesed globals
            change state while executing function, which could only
            happen in a multithreaded environment.
Resolution: Use local variables.
            Note that this change alters function semantics, as now
            function only depends on global values at entry time.
            This shouldn't be a problem, though, as new semantics should
            be in fact better.
