A file is created then three layers to keep simple a red square is created using the marquee tool then filled with a colour this is repeated on the next layer with a different colour then the third layer is completely filled with another colour.
The first two layers are selected and scaled then made transparent.
Finally the layer in between layer 3 and layer 1 is selected and a gaussian blur is applied this is when the corruption occurs

After file is corrupted Photoshop has to be closed and re-opened because subsequent files that are opened are corrupted.
This has been reported in CS5 and CS5.5 extensively but not so much in CS6.
