thread 'tokio-runtime-worker' has overflowed its stack

[begoon]

Version: Deno 1.44.4

I have a complex CLI application to generate PDF's with pdfkit and a few extra libraries.

After the latest Deno update:

deno --version
deno 1.44.4 (release, aarch64-apple-darwin)
v8 12.6.228.9
typescript 5.4.5

everything crashes no matter what with:

cd src/pdf && \
        deno run -A --watch \
        pdf-cli.ts
Watcher Process started.

thread 'tokio-runtime-worker' has overflowed its stack
fatal runtime error: stack overflow

I'm puzzled about how to raise a bug report because I don't know how to supply a simple, reproducible test case.

Also, when I run this project AS IS but with Bun, it works as expected, with no crashes.

Any advice?

I have also realised that in the dockerfile, there is a version of Deno which I didn't upgrade. The application DOES work with that version:

deno --version
deno 1.43.1 (release, aarch64-apple-darwin)
v8 12.4.254.12
typescript 5.4.3

I have downgraded my main CLI deno to 1.43.1, and... the crash is gone.

Something had been broken between 1.43.1 and 1.44.4.

I have bisected the releases and found that the last working release for me is 1.43.5.

In 1.43.6, the application starts crashing because of the error above.

Hello, can you explain how I can re-produce this bug?

What's the script in pdf-cli.ts?

I have isolated the code causing the crash.

I have attached a single file, called crash.ts.

1.43.5 works okay with this file:

// deno upgrade --version 1.43.5

I have checked on linux/amd64 too. The behaviour is the same. It crashes on 1.43.6, but 1.43.5 works.

deno --version
deno 1.43.6 (release, x86_64-unknown-linux-gnu)
v8 12.4.254.13
typescript 5.4.5
