Sometimes simulation workflow log may include panic due to various library errors, like in #135:

Process exit status code is non-zero in this case, hence workflow PASSes.

Describe the solution you'd like

Workflow should FAIL in such cases.

Additional context

It's not critical, however it leads to the fact that we're missing some bugs.
