Teensy 4.1 keeps crashing with this simple code

My code kept crashing after I started using Teensythreads. To get to the bottom of the problem, I kept deleting code until I found the following code. Without threading it does not crash. What might be the problem?
#include <Arduino.h>
#include "TeensyThreads.h"
void setup() {
Serial.begin(9600);
threads.addThread(serialread);
}
void loop() {
// serialread();
delay(500);
}
void serialread(){
int numberOfSegments = 100; // only so i can change it to 2 in manual mode
double x[numberOfSegments];
double y[numberOfSegments];
while(1){
draw_line(0, 0, 0, 0, 100, x, y);
threads.delay(1000);
threads.yield();
}
}
double draw_line(double x1, double y1, double x2, double y2, int NumberOfSegments, double *x, double *y) {
for ( int i = 0; i < NumberOfSegments ; i++) {
x[i] = 0;
y[i] = 0;
Serial.println(y[i]);
}
}

The problem was the DEFAULT_STACK_SIZE = 1024;
. It did not have enough memory to assign to the arrays.
