Hi Michel,
I ran dynare++ on the mentioned mod-file again under Windows++ and used the system monitoring tools for monitoring memory usage. The picture is attached. The blue line shows the percent of memory used of my 8GB RAM on my Laptop from the start until the crash. As you can see, there is not much movement. I do not get anywhere close to the 8GB of memory used for the task that you report for Linux. Rather, straight from the beginning the jnl-file reports 0 available memory and "out of memory". It simply seems as if Dynare++ is hardly using any memory straight from the start. This does not seem to be just a problem of measuring memory usage on Windows.
Best,
Johannes
