Description

### Description of the bug:

I encountered an incremental build correctness issue. When I modify a specific file and run `bazel build`, the build succeeds, but the resulting executable crashes at runtime. However, if I run `bazel clean` and then `bazel build` again, the executable works perfectly.

This suggests that Bazel is using a stale cache or missing a dependency invalidation during the incremental build.

Research direction

The report names no files, tests, or minimal reproducer. First obtain a reproducible incremental-build case on macOS with Bazel 9.1.1 and capture the modified file and build output; done means the incremental build produces an executable that behaves like a clean build after the same modification.
