--- Comment #19 from Martin Jambor <jamborm at gcc dot gnu.org> ---
The following minimized testcase ICEs with r15-312-g36e877996936ab
cross-compiler to ppc64le with -O2 nicely:


void omp_clause_elt_check(int *, const char *, const char *);
enum { C_OMP_CLAUSE_SPLIT_COUNT };
enum c_omp_region_type { C_ORT_OMP };
void c_finish_omp_clauses(int *, c_omp_region_type);
int *c_parser_omp_all_clauses_prev;
int *c_parser_omp_all_clauses(bool finish_p) {
  if (finish_p)
    c_finish_omp_clauses(c_parser_omp_all_clauses_prev, C_ORT_OMP);
  return c_parser_omp_all_clauses_prev;
}
int c_parser_omp_teams___trans_tmp_104;
static void c_parser_omp_teams(int **cclauses) {
  c_parser_omp_all_clauses(cclauses);
  omp_clause_elt_check(&c_parser_omp_teams___trans_tmp_104, "", __FUNCTION__);
}
void c_parser_omp_target() {
  int *cclauses[C_OMP_CLAUSE_SPLIT_COUNT];
  c_parser_omp_teams(cclauses);
}
