However, when I try to run: getProcessedData(rawInts) I get a stackoverflow

error. I don't see why this is. The function code for getProcessedData is very simple: function getProcessedData(rawInts : TRawInts) : TProcessedData; var i: Integer; tempData: TProcessedData; scaleFactor: Double; begin scaleFactor := 0.01; for i := 0 to 65534 do tempData[i] := rawInts[i] * scaleFactor; Result := tempData; end; Why is this causing an error ? delphi stack-overflow share|improve this question edited Mar 27 '14 at 20:04 Zdravko Danev 7,86511535 asked Mar 27 '14 at 19:52 Tim Mottram 199310 When taking the code out of the getProcessedData function and putting it manually in the procedure this error still occurs. In addition to this, the error seem to be thrown when entering getRawData ... I have no clue why this is. –Tim Mottram Mar 27 '14 at 19:57 Local variables are allocated on the stack, and presumably, array[0..65534] of double; is too big, causing a stack overflow. –Blorgbeard Mar 27 '14 at 19:57 Thanks Blorgbeard –Tim Mottram Mar 27 '14 at 19:58 Ok, I'll shorten the array and see if that works. –Tim Mottram Mar 27 '14 at 19:59 1 You are correct. That's a bit of a problem really, as I really need the array of doubles to be that long. Can I extend

What is this stack overflowing? Can it be overcomed or avoided? 1. My program worked for many months. It uses ICS HTTP for browsing activities. 2. Now I added a DShellWindowEvent(ActiveX) to it and after one hour or so, there is an unpredictable stack overflow. When the program is run from Delphi 5, the stack overflow faster. Can I use the TRY...EXCEPT to skip this overflowing? Do Kindly assist! Thank you. kate View Public Profile Send a private message to kate Visit kate's homepage!

Like for example, 2 events trigger eachother, say I put this code in the AfterPost event. Table.Edit; Table.Post; This code will cause a stack overflow, the Table.Post will make the AfterPost event occur , which will then execute Table.Post , and it will continue .... you get a stack over flow error message. This article explains it in more detail, and other reasons why you may get this error. http://community.borland.com/article/0,1410,16373,00.html The best way is to fix this problem, instead of going around it.
