// Tests Google Test's throw-on-failure mode with exceptions disabled.
//
// This program must be compiled with exceptions disabled.  It will be
// invoked by googletest-throw-on-failure-test.py, and is expected to exit
// with non-zero in the throw-on-failure mode or 0 otherwise.

#include <stdlib.h>                     // for exit
#include <exception>                    // for set_terminate

// This terminate handler aborts the program using exit() rather than abort().
// This avoids showing pop-ups on Windows systems and core dumps on Unix-like
// ones.

  // (e.g. TEST and RUN_ALL_TESTS) here.
