[azu]

What version of Bun is running?

0.7.0

What platform is your computer?

Darwin 22.5.0 arm64 arm

What steps can reproduce the bug?

git clone https://github.com/azu/bun-build--tryfabricmartian
cd bun-build--tryfabricmartian
bun install
bun build ./index.ts --compile --outfile mycli
[1]    8254 segmentation fault  bun build ./index.ts --compile --outfile mycli

index.ts:

import { markdownToRichText } from "@tryfabric/martian";

console.log("Hello via Bun!", markdownToRichText);

What is the expected behavior?

output single executable binary

What do you see instead?

segmentation fault

bun build ./index.ts --compile --outfile mycli
[1]    8254 segmentation fault  bun build ./index.ts --compile --outfile mycli

Additional information

https://github.com/azu/bun-build--tryfabricmartian is a reproduce repository.

I noticed this segmentation fault when importing @tryfabric/martian.
It was not a problem with other packages, so there might be something wrong with this package.

Also, bun run works fine.

$ bun run ./index.ts
Hello via Bun! [Function]

Thanks!

I also encountered the same problem when introducing packages. How can I solve it？

[azu]

This issue is resolved in Bun v0.7.1.
