# This page documents known bugs in Dynare stable.
*`model_diagnostics` with the `bytecode` option will crash if the static Jacobian is singular (bug not yet fixed, see !2347)
* Using the `forecast` command with a model solved at `order=2` with `varexo_det`, Dynare would return uncertainty bands based on a first-order approximation (bug not fixed, see #1940)
