backtrace occurs when running a swift test against TestableExe package on Ubuntu 22.04 package build #8955
Description
Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?
- Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands,
swift build,swift test,swift packageetc.
Description
In an Jenkins Ubuntu 22.04 Package build (https://ci.swift.org/job/oss-swift-package-ubuntu-24_04-aarch64/1406),
The TestCommandTests.enableDisableTestabilityDefaultShouldRunWithTestability(buildSystem:configuration:) is failing in using build system swiftbuild and configuration release as a backtrace is occurring when running the swift test ... command, and as such, the output does not contains the expected string.
Expected behavior
The test passes without any withKnownIssue
Actual behavior
