Thanks Johannes. I have fixed the bug in master. It appeared on July 11th only and concerns only the computation of the rank when using check. The fix will appear in Sunday morning's snapshot.

All the best,

Michel

Dear Michel,

I am working on a model where both Dynare 4.2.5 and the most
recent snapshot tell me the BK conditions are verified. However,
4.2.5 says the rank condition is satisfied, while the most recent
snapshot says it is not satisfied.

The reason it that the matrix

w(1:nyf,nd-nyf+1:end)

in dyn_first_order_solver.m contains two rows of 0 that were not
there in dr1.m in 4.2.5. Is there any explanation for this
difference and which version should I trust? The IRFs are the same
in both versions and model_diagnostics does not report any problems.

Best,

Johannes
