[golang/go] cmd/cgo/internal/testsanitizers: TestASAN/asan_global1_fail failures

### ROOT CAUSE The test `TestASAN/asan_global1_fail` is failing because it does not produce the expected memory access error (global-buffer-overflow). This could be due to the compiler optimizing away the code that triggers the error, preventing the sanitizer from detecting it. The test might also be running in an environment where certain optimizations or sanitizer flags are not being applied correctly, leading to the absence of the expected error. ### CODE FIX To address the issue, modify the test to prevent the compiler from optimizing the code that triggers the memory access error. This can be achieved by: 1. **Adding `-gcflags` to disable optimizations**: Use the `-gcflags` flag to disable optimizations for the test, ensuring the code that causes the memory access is not removed or altered. 2. **Marking the function with `//go:noopt`**: Annotate the function causing the error with `//go:noopt` to prevent the compiler from applying optimizations to it. **Example fix for the test**: ```go // In asan_test.go, modify the test function or the code causing the error func TestASAN_asan_global1_fail(t *testing.T) { // Ensure the compiler does not optimize the critical function //go:noopt triggerMemoryError() // Rest of the test code... } ``` **Command to run the test with disabled optimizations**: ```bash go test -asan -gcflags=-N -l cmd/cgo/internal/testsanitizers ``` This ensures the test runs without optimizations, allowing the sanitizer to detect the memory access error as expected. The exact fix may vary based on the test's implementation, but the core issue is the compiler's optimization removing the error-triggering code.
