            Bug ID: 46688
           Summary: omp_pteam_mem_alloc memory "Invalid constantexpr cast"
           Product: OpenMP
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Clang Compiler Support
          Assignee: unassignedclangbugs at nondot.org
          Reporter: xw111luoye at gmail.com
                CC: llvm-bugs at lists.llvm.org

In the following example,
  T base[2];
  #pragma omp allocate(base) allocator(omp_pteam_mem_alloc)
  compute_prefactor(team_id, base);
calling function compute_prefactor with the base caused compiler error.
