Re: [Quantlib-dev] Issues with C# Swig Bindings, NUnit and Settings.instance().setEvaluationDate()

Hi Luigi,

I have a similar call stack which also seems to error at
notifyObservers(Line119). I truncated the C# bits.

  msvcr90d.dll!1023c355()
  [Frames below may be incorrect and/or missing, no symbols loaded for
msvcr90d.dll]
  msvcr90d.dll!1023e1fa()
