+//! \brief Wraps the gtest `ASSERT_DEATH()` macro to make assertions about death
+//!     caused by `CHECK()` failures.
+//!
+//! In an in-Chromium build in the official configuration in Release mode,
+//! `CHECK()` does not print its condition or streamed messages. In that case,
+//! this macro uses an empty \a regex pattern when calling `ASSERT_DEATH()` to
+//! avoid looking for any particular output on the standard error stream. In
+//! other build configurations, the \a regex pattern is left intact.
