Stack overflow in (null)

When I run the case, I get a stack overflow in (null) error.I tried unchecking SMP when building the solver, but that didn’t solve the problem!I don’t know how to fix it, can you check it for me?
Thank you very much!

I haven’t looked at your code yet but “Stack overflow” typically results from a function or subroutine calling itself, either directly or indirectly

When I run this I do not get a stack overflow, I get

Error from check_data_30.f:672
Fatal Error: Unphysical field variables detected.
     I      J      K
     5      3      2      X_G(6) =  -0.9966E-07 <   0.000
