For the record, I had a closer look at this. It seems to be a bug in
my system compiler on Ubuntu 11.04, gcc (Ubuntu/Linaro 4.5.2-8ubuntu4)
4.5.2.

In this code from unittests/AST/APValueTest.cpp:

  template<typename T>
  std::string operator()(const T& value) {
    Diag.Report(diag_just_format) << value;
    return LastDiagnostic.get().str();
  }

... the compiler is failing to call the destructor for the temporary
DiagnosticBuilder returned from Diag.Report(diag_just_format).

If I compile the test with gcc 4.6.1 (which I built from source) the
problem goes away.

Jay.
