Bun crashes during fetch request (seg fault at address 0x0)

Abhinav5383 commented 1 month ago

How can we reproduce the crash?

I don't have a good idea how it happened, but it probably happened due to the device losing internet just after bun made a fetch request.

Relevant log output

Nope, couldn't reproduce either on the version I was or on the latest version
