Segmentation fault at address 0x5

[vdata1]

How can we reproduce the crash?

Hi,

I want to report a bug causing a segmentation fault in Bun, it can reproduced by running the following code example:

function Module() {
  (async function () {
    const output = await (Bun.$)`pwd`.text();
    console.log(output);
  })();
    new Float64Array(badObj);
}
function f() {
  try {
    var fuse = f();
    if (fuse == 0) Module();
  } catch (e) {
    return 0;
  }
}
f();

Regards,

AH
