//! \brief Wraps the ASSERT_DEATH_CRASH() macro to make assertions about death

//! In an in-Chromium build in the official configuration, `CHECK()` does not

//! empty \a regex pattern when calling ASSERT_DEATH_CRASH() to avoid looking
//! for any particular output on the standard error stream. In other build
//! configurations, the \a regex pattern is left intact.
//!
//! On macOS, `CHECK()` failures normally show up as crashes to the system’s

//! crashes to be handled by any crash reporter, so this is implemented in
//! terms of ASSERT_DEATH_CRASH() instead of `ASSERT_DEATH()`.
