Code not running at exit

[victorliu]

On Mac OS 12.5.1 (on Apple silicon), modifying the minimal white noise example to the following:

// main.c
#include "fenster.h"
#define W 320
#define H 240
int main() {
  uint32_t buf[W * H];
  struct fenster f = { .title = "hello", .width = W, .height = H, .buf = buf };
  fenster_open(&f);
  while (fenster_loop(&f) == 0) {
    for (int i = 0; i < W; i++) {
      for (int j = 0; j < H; j++) {
        fenster_pixel(&f, i, j) = rand();
      }
    }
  }
  printf("here\n");
  fenster_close(&f);
  return 0;
}

Does not print "here" when the window is closed. This is the output of cc -v:
