Again investigate memory problems with k_order_perturbation on Windows
Two users at https://forum.dynare.org/t/cant-work-with-third-order/10523/12 report problems with Dynare 4.5.1. I cannot replicate the issue on my machine.
The stack trace on both affected machines is

So it might have to do with Visual Studies's msvcrt.dll
and the random number generator's call to the system time.
