The new binaries built with Static Linux SDK crashes #6287
Description
New Issue Checklist
- I've Updated SwiftLint to the latest version.
- I've searched for existing GitHub issues.
Bug Description
A fully statically linked binary named swiftlint-static that does not require
any dynamic libraries at runtime. Rules requiring SourceKit will be disabled and
reported to the console when running this binary.
https://github.com/realm/SwiftLint/releases/tag/0.61.0
I have tried this new binary for Linux hoping that we can simply run SwiftLint on plain ubuntu env on GitHub Actions.
It crashed with segmentation fault when linting some code. This seems to occur on both AMD64 and ARM64.
$ ./swiftlint-static
Linting Swift files in current working directory...
....
Linting 'xxxx.swift' (57/616)
Segmentation fault (core dumped)
To reproduce the issue, I did set up Linux environment with Swiftly. I managed to get minimum input file that can reproduce the crash on linting and some backtrace by building static linux sdk binary with 0.61.0 tag locally.
Environment (I used VMware Fusion with Ubuntu Desktop image on macOS so it's ARM env)

Bug.swift that I used above is this (redacted one from actual source code from our project but still make it crash).
import Foundation
import UIKit
class CustomTextField: UIView {
private lazy var stackView: UIStackView = {
let stack = UIStackView(
axis: .vertical,
alignment: .fill,
distribution: .fill,
spacing: .s,
subviews: [
UIStackView(
axis: .vertical,
alignment: .fill,
distribution: .fill,
subviews: []
),
]
)
return stack
}()
}This of course doesn't make SwiftLint crash on macOS nor Ubuntu with normal debug build binary.
Environment
- SwiftLint version 0.61.0 / swiftlint-static for ARM64/AMD64
- Xcode version N/A
- Installation method used from GitHub Release page
- Configuration file: The issue persists with no config file
