### Summary Stabilize ASan wchar tests across Darwin and Android. NFC: test-only. Follow-up to PR #160493 (adds wchar interceptors/tests). ### Motivation - Darwin: The top frame often resolves to `libclang_rt.asan_*` rather than a source file, so strict checks that include file/line can fail. See Chromium issue [448631142](https://g-issues.chromium.org/issues/448631142). - Android: The “ERROR:” header can go to logcat instead of stderr, so FileCheck may not see it; stdout/stderr reordering also makes pre-crash markers racy. See Android Buildbot [186/12821](https://lab.llvm.org/buildbot/#/builders/186/builds/12821). ### Changes - Android: - Force reports to stderr via `%env_asan_opts=log_to_stderr=1`, avoiding the “ERROR:” header going to logcat. - Print the pre-crash “Good so far.” to stderr and `fflush(stderr)` to avoid stdout/stderr reordering. - Darwin: - Relax the stack-frame check to only require the function name (`wcscpy/wcsncpy/wcscat/wcsncat`) to tolerate `libclang_rt.asan_*` frames. - Common: - Reuse FileCheck var `[[ADDR]]` instead of redefining. - Make wide string literals `const wchar_t*` to silence `-Wwritable-strings`. ### Risk - NFC: test-only; no change to runtime behavior. ### References - Follow-up to PR #160493. - Chromium: [448631142](https://g-issues.chromium.org/issues/448631142) (Darwin failures). - Android Buildbot: [186/12821](https://lab.llvm.org/buildbot/#/builders/186/builds/12821).
