CUFFT cudaError_enum using v3_1 toolkit FFT works but get lots of cudaError on plan creation

Hi,

Really stumped with this one. Have installed toolkit and SDK v3.1 on four different machines. Three of which are XP and one is Windows 7. I am trying to use the CUFFT library and it worked fine with V2.2 of the CUDA toolkit/SDK, but I needed to upgrade to v3.1 so I can use the planMany feature to batch process lots of 2d ffts.
I have found that on all my machines with compute capability 1.2 or less, I consistently get the error message from Visual Studio 2008,

“Microsoft C++ expception: cudaError_enum at memory location xxxxxxxxx”
it comes out about 15 times during the plan call.

I dont get the error message on a machine that has a GPU of compute capability 1.3. This may or may not be related.

This error occurs on the Windows XP and Windows 7 machines, so its not OS related.
I have tried different device drivers but to no avail. I have also tried v3.2 of SDK/Toolkit and same problem.

If I ensure that I dont make any use of the CUFFT library, the error message goes away. I am using plenty other cuda features.

Even with the error the FFT does actually work though, but the string of errors is a bit unnerving.

Any help very welcome!
