* gimplify.c (gimplify_scan_omp_clauses): Remove special casing
of INDIRECT_REF RESULT_DECL.

* cp-gimplify.c (cp_genericize_r): Don't dereference invisiref
parameters and result decls in omp clauses.

by reference.

[Bug c++/30703] ICE Segmentation fault on using OpenMP

--- Comment #2 from jakub at gcc dot gnu dot org  2007-02-06 10:11 ---
Simplified testcase:
struct A
{
  A() {}
  ~A() {}
  int i;
};

void
foo (A a)
{
#pragma omp parallel firstprivate (a)
  a.i++;
}

The problem is that while OpenMP 2.5 prohibits firstprivate etc. vars having
reference type (and we properly diagnose it), cp_genericize_r changes
TREE_ADDRESSABLE class parameters to reference type internally and this is
something cc1plus should handle.
