// gcc/icc target offloading is incompatible with libomp
// UNSUPPORTED: icc, gcc
 
// The test checks that "devide-by-0" bug fixed in runtime.
// The fix is to increment number of threads by 1 if positive,
// so that operation
//   (gtid) % (__kmp_hidden_helper_threads_num - 1)
// does not cause crash.
