crash when terminate libcheck process (with subprocesses)

I am trying to debug c code with libcheck. When I run project and terminate it using "red stop button" in QtCreator then Qt creator is unexpectly terminated (Actually I am not sure if segfault).

The reproducer code is based on https://github.com/libcheck/check/tree/master/doc/example - I am running ./tests/check_money (see attachment) extended with:

START_TEST(test_money_sleep)
{
    sleep(100);
}
END_TEST

tcase_set_timeout(tc_core, 200.0); 

It seems the qtcreator is not crashing when is set

srunner_set_fork_status (sr, CK_NOFORK);
