[Bug c++/44808] New: ICE: tree check: expected var_decl, have result_decl in gimplify_modify_expr

[marc dot glisse at normalesup dot org]

The following code produces the error:

$ c++    -c triangles_test.cpp  -O9
triangles_test.cpp: In member function ‘virtual Halfedge_handle
Ovl_visitor::insert_at_vertices()’:
triangles_test.cpp:12:24: internal compiler error: tree check: expected
var_decl, have result_decl in gimplify_modify_expr, at gimplify.c:4571
Please submit a full bug report,

I checked with a snapshot from the 3rd of July, so this shouldn't be the same
as bug 44706 (the closest thing I could find in bugzilla).

struct Halfedge_handle
{
        void *a,*b;
        int c;
};

struct Ovl_visitor
{
        virtual Halfedge_handle insert_at_vertices ()
        {
                Halfedge_handle res;
                Halfedge_handle he = res;
                return res;
        }
};

Ovl_visitor               visitor ;
