'Infragistics.Win.CalcEngine.UltraCalcException' occurred in Infragistics4.Shared.v17.2.dll

    I can reproduce this with 16.2.2182 SR.  I reverted back to 16.2.1000 and could not repro.  Also could not repro with 16.2.2111.   It looks like this was introduced in the latest SR and 17.2.  

    My code hits this when I do an Export to Excel, but it looks like it is because there is a recalc that causes the exception. 

    Here is the stack trace:
