When `--serialize-diagnostics` is used, `SDiagsWriter` enters bitstream blocks during its initialization. They are expected to be exited in the `finish()` method. However in LibTooling based tools (like `clang-tidy` or `clang-check`), if a user provides an invalid command-line argument, the driver detects the error and prepares for an early exit. The exit path leads directly to destruction, skipping the call to `finish()` that would normally occur in the main logic. Then the assertion detects this block imbalance and triggers a crash.
