Default udf problem with Loe-Re Stress-Omega

m.reza is on a distinguished road
When I use the dissipation rate (e) in my udf and choose Low-Re Stress-Omega , fluent gives "ACCESS_VIOLATION" error.
for example I want to add a source term like below to energy eq.

and when I change e with omega in my udf ,fluent gives floating point error.
when I choose linear or quadratic pressure-strain(Reynolds Stress Models) , I don't have any problems.

Do you help me?
