matlab crash when I used API in system verilog

Hi, I want to use the API C functions from matlab to import them in a system verilog environment. I succeed to do that. I also can access the variables from matlab environment, but if I want to dump some simulation waves in IUS ( Cadence simulator) I get a crash from Matlab.

A technical support engineer might contact you with further information.

I'm not sure if it is a matlab issue or a IUS issue but I want your opinion.

Thank you !
