<div dir="ltr">You can make these changes (one from IOhannes and two of my suggestions in-line below) and see if the error is gone. My guess is: probably not. I didn't see any glaring problems that would cause memory corruption. <br>
<br>Could you also show us your rhynamo_set(symbol, float) function? Does the error occur *only* after the set function gets used? <br><div><br>If for some reason, these small changes do fix your issue, just back up and make one change at a time, and check if you can reproduce the error each time. I'd be interested to know what actually causes it.<br>
