// By default, GTest (on Windows) installs a SEH filter (and a handler) before
// starting to run all the tests in order to avoid test interruptions is some
// of the tests are crashing.  Unfortunately, this functionality prevents the
// execution to reach the UnhandledExceptionFilter installed by Google-Breakpad
// ExceptionHandler so in order to test the Google-Breakpad exception handling
// code the exception handling done by GTest must be disabled.
// Usage:
//
//  google_breakpad::ExceptionHandler exc(...);
//
//  // Disable GTest SEH handler
//  testing::DisableExceptionHandlerInScope disable_exception_handler;
//  ...
//  ASSERT_DEATH( ... some crash ...);
