Hi all,
I've reproduced this crash in LabVIEW 2010 SP1 and have passed this along to our R&D team. A Corrective Action Request (CAR) has been filed as CAR # 309566.
I'm glad that you were able to find the workaround by simply wiring the unwired feedback node and OR inputs, but I wanted to make you aware that this is something that we're addressing.
Thanks for bringing this to our attention!
Regards,
