// Unit test for Google Test's break-on-failure mode.
//
// A user can ask Google Test to seg-fault when an assertion fails, using
// either the GTEST_BREAK_ON_FAILURE environment variable or the
// --gtest_break_on_failure flag.  This file is used for testing such
// functionality.
//
// This program will be invoked from a Python unit test.  It is
// expected to fail.  Don't run it directly.
