--- Comment #3 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
One finding:
In trees_out::decl_node, there are code lines:
case FIELD_DECL:
{
if (streaming_p ())
i (tt_data_member);
tree ctx = DECL_CONTEXT (decl);
tree_node (ctx); //The context, is the struct "S" inside foo, "S" is
handled in 'tree_node', and "insert" is called for member "d".
tree name = NULL_TREE;
if (TREE_CODE (decl) == USING_DECL)
;
else
{
name = DECL_NAME (decl);
if (name && IDENTIFIER_ANON_P (name))
name = NULL_TREE;
}
tree_node (name);
if (!name && streaming_p ())
{
unsigned ix = get_field_ident (ctx, decl);
u (ix);
}
int tag = insert (decl); //HERE, "insert" is called again member "d".
It may be a direct cause that "insert" is called twice for "d", and then a
crash occurs.
While I do not know much about the code and do not found a fix.
