[golang/go] cmd/cgo/internal/testsanitizers: TestASAN failures

### ROOT CAUSE The issue arises from the `TestASAN` test in the `cmd/cgo/internal/testsanitizers` package, which fails during the build process when executed with ASAN (AddressSanitizer). The error indicates that the build command exits with status 1, likely due to a segmentation fault or memory corruption in the standard library code when compiled with ASAN flags. This could stem from a bug in the standard library or a test case that triggers undefined behavior under ASAN instrumentation. The provided research context shows similar issues (#74726, #72766, #72723) related to sanitizer tests, suggesting potential underlying problems in the test infrastructure or sanitizer integration. ### CODE FIX Due to insufficient context (lack of stack traces, detailed error logs, or specific code snippets) and the complexity of ASAN-related failures, a targeted fix cannot be provided. The issue requires deeper investigation into the standard library's behavior under ASAN, including: 1. Enabling detailed ASAN output (e.g., `--asan-fast-unpoison=false` or `--asan-poison-after-free=false`) to capture memory-related errors. 2. Adding explicit checks for panics or crashes in the `TestASAN` test. 3. Reviewing the standard library's build flags and ensuring compatibility with ASAN. Without additional information, a safe code fix cannot be implemented.
