[aspect-devel] Error from violated condition on parameters

Sorry for the bad advice.
I thought that DEBUG mode is useful to reveal errors in the code only, but not in a particular model setup...

Let me put this differently: It is a bad idea in general to run something in optimized mode if you haven't made sure that it runs without problem in debug mode -- you miss out on so many warnings and errors for bugs that are much easier to find in debug mode.

It is a *terrible* idea to run in optimized mode *if you know that there is an error in your code*. It is equivalent to seeing a warning light in your car that says that your brakes don't work, and to respond to it by disconnecting the light's power supply. Only bad things can happen to your car if you do this. Only bad results can happen if you purposefully ignore an error from ASPECT that you do not understand fully.
