The debugger dies when the method get_properties is invoked. As I said before, this error is not especific to this code. Looks like this issue happens depending on the amount of objects the program uses simultaneously.

Here is more code regarding the get_properties method:

The get_sibling method returns a DynamicPropertiesTask object, as specified in the MS SQL 8 DTS documentation. For each assignment fetched with the in function, a new object is instantied.

I could try to create a iterator instead creating all assignments objects at once in the get_properties method, but this should be a performance enhancement, not a bug fix IMHO.

I tried running the program using the debugger again just to be sure. A nice (?) window asking me to report the error to Microsoft is opened. The only useful information I could find in the details is the information below:

AppName: perl.exe	 AppVer: 5.8.8.819	 ModName: ole.dll
ModVer: 0.0.0.0	 Offset: 00001f98

I never tried Win32::OLE to do more than writing some stuff in a MS Word document, so I cannot say this is an issue caused by Win32::OLE plus DTS API or only the Win32::OLE itself.
