Steps to reproduce this
Steps:
  1. Run the following sketch in the p5.js editor

Doing this yields Error: Multiple infinite loops detected. Stopping execution.

Snippet:

const points1 = [];
const num = 7;

function setup() {
  const s = 640;
  createCanvas(s, s, WEBGL);
  for (let i = 0; i < num; i++) {
    const x = 0.5 * width - random(0, width);
    const y = 0.5 * height - random(0, height);
    const z = 0.5 * width - random(0, width);
    points1.push({
      x: 0.625 * x,
      y: 0.625 * y,
      z: 0.625 * z,
    });
  }
  frameRate(24);
}

function draw() {
  background(15);
  noFill();

  for (let k = 0; k < 32; k++) {
    stroke(255);
    push();
    rotateY(frameCount * 0.01 - k * 0.04);

    beginShape();
    for (let i = 0; i < points1.length; i++) {
      splineVertex(points1[i].x, points1[i].y, points1[i].z);
    }
    endShape(CLOSE);
    pop();
  }
}

Research direction

Start by running the supplied sketch in the p5.js editor and trace the splineVertex entry point through the WebGL/core rendering path. Done means the reproduction no longer reports “Multiple infinite loops detected” while drawing the closed spline.
