ADAU1466 compiler error?

I'm just playing around using the Sigma Studio V3.15 Beta 2 and a ADAU1466 chip.

I'm using some delays in my design but the compiler issues an error message if I try to use more than 32K per data memory.


The compiler_output.log says

##### Summary #####
DM0 RAM used:       32016    (of 40960)
DM1 RAM used:       29741    (of 40960)
PM  RAM used(Data): 00000    (of 24576)
PM  RAM used(Inst): 00324    (of 24576) 246 instructions (32bit: 168  64bit: 78)
Total PM used:      00324    (of 24576)


If I try to add another delay block that exceeds 32K in one of the data memories I get an error message:

"Assembler Error. Object reference not set to an instance of an object."


What could be the problem here?
