Hi guys, this is the root cause of this thread -CPU Exception when Study is triggered.

I have attached the simplest possible code that triggers a replay using acsil below. When ran it throws the error below:

#include "sierrachart.h"

SCDLLName("PhitechBacktest");

SCSFExport scsf_TriggerBacktest(SCStudyInterfaceRef sc)
{
SCInputRef i_enabled = sc.Input[2];

if (sc.SetDefaults)
{
sc.GraphName = "Trigger Backtest";
sc.StudyDescription = "Phi Technologies study for Sierra.";
sc.AutoLoop = 0;
sc.GraphRegion = 0;

i_enabled.Name = "Enabled";
i_enabled.SetYesNo(true);
return;
}

if (not i_enabled.GetYesNo())
return;

SCDateTime start;
start.SetDateTimeYMDHMS(2024,9,9,13,0,0);
sc.StartChartReplay(sc.ChartNumber, 30.0, start);
i_enabled.SetYesNo(false);
}

To be honest, this error is not impacting the functionality of my studies, i.e. functionally mu studies do exactly what i expect when running replays, but I just want to be certain this is not impacting sierra in some unknown way that would end up being detrimental to my backtests.

I am not sure if my spec has anything to do with this but here we go -> Windows 11 with Nvidia 16GB VRAM, 32 GB Ram 12 core i7 processor, SSD drive.

I'd really be interested to get to the bottom of this, so any pointers are welcome.

P.S.
It doesn't matter whether I use sc.StartChartReplay or sc.StartChartReplayNew...
