We need to do this because we have tests which create Files from a raw fds or do an explicit close on fds. This causes UB check to trigger and test to panic. There is no separate flag to disable these checks, so we have to disable all debug-assertions in test builds. Tracking issue: rust-lang/rust#123499 Signed-off-by: Egor Lazarchuk <[email protected]>

The feature gate for the issue is
#![feature(ub_checks)].It allows write code that detects if the compiler will emit UB checks, simlar to how `cfg(debug_assertions) detects if debug assertions are enabled.
We also track the
-Zub-checksflag here; that should eventually become-Cub-checkssimilar to-Coverflow-checks.About tracking issues
Tracking issues are used to record the overall progress of implementation.
They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.
A tracking issue is however not meant for large scale discussion, questions, or bug reports about a feature.
Instead, open a dedicated issue for the specific matter and add the relevant feature gate label.
