I cannot reproduce this on i686-pc-linux-gnu for some reason... last changelog
entry is
2005-07-05  Kazu Hirata  <kazu@codesourcery.com>

        * Makefile.in (stamp-as): Use $(ORIGINAL_AS_FOR_TARGET)
        instead of $<.  Don't remove ./as if it already exists.

so Daniel Berlin's fix for PR 22279 is already in.

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-07-05 18:06 -------
Confirmed, reduced as far as I can get it:
struct location
{
  int x, y;
};
struct defensive_position
{
  int chance_to_hit;
  long long vulnerability, support;
};
template<class _T1, class _T2> struct pair
{
  _T1 first;
  _T2 second;
  pair();
  template<class _U1, class _U2> pair(const pair<_U1, _U2>& __p)
  : first(__p.first), second(__p.second){}
};
struct map
{
  typedef pair<const location, defensive_position> value_type;
  void insert(const value_type& );
};
map defensive_position_cache_;
void best_defensive_position()
{
  defensive_position_cache_.insert(pair< location,defensive_position>());
}

> Confirmed, reduced as far as I can get it:

One more thing, this testcase also fails on 32bit ppc-darwin and 64bit ppc-darwin.
