IPP 2019 Update 1 DFT Length Limit?

Using IPP 2019 Update 1, I get a ippStsSizeErr error whenever I call either of the following functions with a length that's greater than 2^26 (67,108,864).

ippsDFTGetSize_C_64fc()

ippsDFTInit_C_64fc()

This length limit isn't documented anywhere. Is it expected behavior?

This article indicates that the length limit for the DFT is 2^32: https://software.intel.com/en-us/articles/mkl-ipp-choosing-an-fft

Thank you for your time.
