[Bug middle-end/30494] ICE with VLA and openmp

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2007-01-18 10:13 -------
Confirmed, reduced testcase (I thought I had asked about this interaction
before):
int Birkhoff_with_Vol_para(int n)
{
  int I;
#pragma omp for
        for(I = 0; I < 6; I++) 
        {
                int v[n];
        }
}

--------
This ICEs for both the C and C++ front-ends.  Considering VLA is C99, we should
support this.  Also I bet you can produce a fortran code which also ICEs.
