Suffering from error 111

Suffering from error 111 - 03/15/17 15:01

My script gives
Error 111: Crash in script: compramosSpread();

This error only happens after having run an optimization, with the "Train" option and then clicking on "Backtest".

If I comment out the lines
Code:
set(PARAMETERS);
DataSplit = 80;
NumWFOCycles = 10;


then the backtest works ok, no error is shown. I have looked for the obvious: errors in code, wrong array indexes or divisions by zero, but I think I don't have any of these...

I think the problem is in exceeding the stack size, and I think I know why.
This is the optimize line that makes the script fail:

Code:
int lookBacks[5] = {150,300,450,500,700};
LookBack = lookBacks[optimize(0,0,4,1)];


But if I change these lines with this, it doesn't crash:

Code:
int lookBacks[3] = {150,300,450};
LookBack = lookBacks[optimize(0,0,2,1)];


Do this make sense to you? Can I upsize the stack value in Zorro Trader?
I am only optimizing one parameter, with 3 possible values. Is it normal that with 5 possible values the stack gets full and makes the script crash?

You can not exceed the stack size this way, so the problem is somewhere else. But it's a hint that is seems to depend on the lookbacks value. Check for exceeding the length of a series somewhere.

The crash happens inside the compramosSpread function, so it should be easy to find which line it is, by placing watch or print(TO_FILE,..) statements in the function.
