Simplified testcase:
struct S
{
S ();
~S ();
int s;
};
void bar (S);
void
foo ()
{
S s;
#pragma omp parallel shared (s)
bar (s);
}
Works if s is firstprivate or private, or if it doesn't have user defined
destructor.

------- Comment #6 from jakub at gcc dot gnu dot org 2008-02-15 21:07 -------
The problem is the regimplifying done by lower_omp_1.
We have
D.NNNN = s;
where both of the vars have RECORD_TYPE with TREE_ADDRESSABLE types.
lower_omp_1 sees on the right hand side VAR_DECL with DECL_VALUE_EXPR
(wi->is_lhs = false, wi->val_only = true), which is replaced with
*.omp_data_i->s which doesn't satisfy is_gimple_val predicate lower_regimplify
uses and of course the compiler isn't allowed to create temporaries of
TREE_ADDRESSABLE types on its own. In this case I believe we need to force
the .omp_data_i->s address into a temporary first and then *temp should
hopefully satisfy the predicate. Diego, any ideas?

gcc44-pr35185.patch
WIP patch I'm playing with. It just looks for statements that reference
variables with DECL_HAS_VALUE_EXPR_P and regimplifies them as whole, rather
than
only regimplifying parts of them.
I still get 4 libgomp regressions:
FAIL: libgomp.c/nestedfn-4.c execution test
FAIL: libgomp.c/pr33880.c execution test
FAIL: libgomp.c/pr35130.c execution test
FAIL: libgomp.fortran/pr35130.f90 -O execution test
and most likely further work will be needed for -ftree-parallelize-loops
where lower_omp is called on SSA.
