the problem of using cuMemcpyPeer

I want to copy the data from a buffer in the device memory with a context to another buffer in the device memory with another context.

When I use the driever api
CUresult cuMemcpyPeer ( CUdeviceptr dstDevice, CUcontext dstContext, CUdeviceptr srcDevice, CUcontext srcContext, size_t ByteCount )

my application will crash.

the driver version is 373.06 and the date of published is 10/06/2016. My video card is gtx750.

Is there any people who has the same problem?
