[jira] Commented: (STDCXX-87) [Sun C++ 5.9] RUI in std::set::insert()

["Martin Sebor (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/STDCXX-87?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12580951#action_12580951 ] 

Martin Sebor commented on STDCXX-87:
------------------------------------

Here's a reduced test case to narrow it down:
{noformat}
#include <cassert>
#include <set>

int main ()
{
    typedef __rw::__ident<int, int> Ident;
    typedef std::less<int>          Less;
    typedef std::allocator<int>     Allocator;

    typedef __rw::__rb_tree<int, int, Ident, Less, Allocator> Tree;

    Tree x;

    std::pair<Tree::iterator, bool> ret;

    x._C_insert (0, ret, false);

    assert (1 == x.size ());
}
{noformat}

Reduced dbx output for this test case (with uninteresting detail removed):
{noformat}
