Compiler crashes

I am writing a Function under Create function and with the following code, the compiler simply hangs and I have to kill the program through task manager.

----------------------------------------------------------------
int i,j;

int cycle_StartDateYear = 1929;
int cycle_StartDateMonth = 1;
int cycle_StartDateDay = 1;
int cycle_DurationYears = 18;

VectorDate barDate = cFunctions.Date;

i=0;

while(true)
{
if ( barDate[i].Year == cycle_StartDateYear )
{
if (i>=result.Length) break;

for(j=0;j<18;j++)
{
result[i] = j;
i++;
}

}
}

Best Answer

This function will loop infinitely.

The "year" condition will always return "false" because "i" will always be equal to 0 (The update is done after the condition check which is wrong)
barDate[i].Year == cycle_StartDateYear

I understand the flaw in Logic, but what I dont understand is that why should the editor crash?

Shouldn't my logic flaw be obvious when I don't see the expected results?

I did not do anything wrong with respect to syntax right?

Scripts created using "Create function" tool are executed in the main thread (Unlike others).

A function that loops infinitely will make the application unresponsive and this will ultimately crash it.
