There is a known bug in ICC with respect to passing 16-byte aligned types by value to GCC-built code such as the CUDA Toolkit libraries (e.g., CUBLAS). At this time, passing a double2 or cuDoubleComplex or any other 16-byte aligned type by value to GCC-built code from ICC-built code will pass incorrect data. Intel has been informed of this bug. As a workaround, a GCC-built wrapper function that accepts the data by reference from the ICC-built code can be linked with the ICC-built code; the GCC-built wrapper can then, in turn, pass the data by value to the CUDA Toolkit libraries.
