Large numbers crash Seasonal Adjustment

Using Tramo-Seats on the attached debt data for Belgium crashes Eviews 8.1 when using Tramo-Seats. The reason seems to be that Tramo cannot handle large numbers. Dividing everything by 1E8 alleviates the problem. It would be great if Eviews could provide the associated error messages instead of simply crashing.

Unfortunately since we do not write Tramo/Seats, there is little we can do to contain the errors caused by Tramo/Seats. If Tramo/Seats crashes, it does have a knock on effect that then crashes EViews.

I understand that you cannot fix the underlying problem, but crashing the program means that there is poor exception handling in Eviews. It should be possible to check whether Tramo/Seats outputs any files. If not, abort with an error message.

Unfortunately Tramo is a DLL, not a completely stand alone executable. It is pretty much impossible to exception handle a DLL like Tramo.
