1.1.27 `bun --bun run docusaurus build --no-minify` segfaults

[o-l-a-v]

How can we reproduce the crash?

Windows 11 23H2, Bun v1.1.26, PowerShell v7.4.5 -noprofile, Docusaurus 3.5.2.

Reproduce:

• cd "$env:USERPROFILE\Desktop"
• mkdir tes
• cd tes
• bun create docusaurus@latest, choose classic as template, and JavaScript (vs. TypeScript), rest as default.
• cd website
• bun install
• bun --bun run docusaurus build --no-minify

Bun crashes and removes content in the terminal, so had to take a screen recording instead. Screenshot of the screen recording:
