Describe the bug

I'm running swiftlint analyze with rules explicit_self and unused_import enabled in my project: https://github.com/gereons/SwiftLintBug1 (use the enclosed lint.sh to reproduce).

Expected result: swiftlint consistently reports the violations in all ten runs

Actual results vary. Most runs report Could not get cursor info twice, and find no violations. Some runs report Could not get cursor info once, and find explicit_self violations in one file. Rare runs do not report Could not get cursor info at all and correctly find violations in two files.

When either of the analyzer rules is commented out in the .yml, the remaining rule works correctly.

Swiftlint version: 0.38.1, installed via homebrew
Xcode version: 11.3

Interesting. In all my projects I usually run one rule at a time, which could explain why I haven't seen this.
