so there is an issue with gimplification of type sizes of VLA.

------- Comment #1 from reichelt at gcc dot gnu dot org  2009-05-06 06:59 -------
Confirmed. Simple testcase (just compile with -fopenmp:

=====================================
void foo(int n)
{
  int x[n];

  #pragma omp parallel private(x)
    x[0] = 0;
}
=====================================

Only the C++ frontend seems to be affected, not the C frontend.
