It also happens with 1.47.3.
Code:
function run() {

 StartDate = 2009;
 EndDate = 2015;
 BarPeriod = 1440;

 asset("EUR/USD");
 var EURUSD = (priceClose() - price()) / priceClose();

 asset("GBP/USD");

 if(EURUSD > 0)
	reverseShort(1);

 if(EURUSD < 0)
	reverseLong(1);

}


Changing BarPeriod causes a 030 error or it crashes completely. After restart Zorro executes the strategy.
