Good morning all,

Due to the current quantlib compiler settings, access violations are not caught with catch(...)
as a result we can have some rather ungraceful crashes.

I wonder are there reasons why the settings are the way they are?

I'd suggest changing the settings.
To do this in MS Visual C++ 2008, click on:
   Project -> Properties -> Configuration Properties -> C/C++ -> Code Generatoin
and set: 
   Enable C++ Exceptions 
to
   Yes With SEH Exceptions (/EHa)
rather than
   Yes ( /EHsc)

Here are some details of the compiler settings:

Right now, when I use the quantlib XL addin in excel ( 2007 ) as excel is closes it crashes ( almost always).
There are two problems with this,
1: some error is thrown
2: the error is not caught

By changing the settings above we can at least solve number 2.

Cheers
Philip
