I'm running the file attached here, where I've just deleted the plots at the end, commented out 'stoch_simul' and commented back in the estimation portion.
Using Dynare 4.4.3, I get the error quoted below.
Also, while I've got your attention, I think the current 'Ireland_2004.mod' file on your Github has a typo on line 172 in the estimated params block (omega isn't specified and I couldn't run it as is)
STEADY: numerical initial values or parameters incompatible with the following equations
1 2 4 5 6 8
Check whether your model in truly linear

Error in computing likelihood for initial parameter values
ESTIMATION_CHECKS: There was an error in computing the likelihood for initial parameter values.
ESTIMATION_CHECKS: You should try using the calibrated version of the model as starting values. To do
ESTIMATION_CHECKS: this, add an empty estimated_params_init-block with use_calibration option immediately before the estimation
ESTIMATION_CHECKS: command (and after the estimated_params-block so that it does not get overwritten):
