It's a numerical problem. For example, if you multiply your eubor_3m 
variable (and its lags) by 10, the problem disappears. The same happens 
with ifo_r1_dln.

It looks as if with the original values some weird condition is triggered 
such that the Hessian turns out to be numerically singular. I'll look into 
this.
