[PATCH] : PR libstdc++ 3349

[Sylvain Pion]

Hi,

This trivial patch fixes PR 3349, a 2.95 regression, concerning a bug in
std::map.insert(hint, value).  It just reverts the code to what was in old
versions, presumably before changes made by John Potter in 1999.  I couldn't
access the mail archives of libstdc++ from that time (broken links), and I
couldn't find where this file was before, so couldn't "cvs annotate" to tell
why exactly this change was made.  Someone who knows should probably double
check.  Here's a test-case for the test-suite :

void test()
{
  typedef std::map<int, int> Map;
  Map M;
  Map::iterator hint;
  hint = M.insert(Map::value_type(7, 0)).first;
 
  M.insert(hint, Map::value_type(8, 1));
 
  if (M.find(7) == M.end())
    abort();
}
