egcs-1.0.1 problem on aix4.2

["Craig J Copi" <copi at erebus dot phys dot cwru dot edu>]

	I have encounted a problem compiling some c++ code that uses a few stl
containers.  A short sample of that creates the problem is included below.  I
haven't seen any comments on this so I'm concerned that I compiled/installed
egcs improperly.  Any insight would be appreciated.  I can send more
information if needed.  The code I tested compiles find under aix4.2 with
egcs-1.0 and under solaris2.5.1 with egcs-1.0 and egcs-1.0.1.

We require two programs:
tmp.c++:
--------
#include <vector>

vector<double> junk ();

int main ()
{ 
  vector<double> a;
  a = junk ();
  return 1; 
}
----------------------------------------
tmp1.c++
--------
#include <vector>
vector<double> junk ()
{
  vector<double>b (2, 0.0);
  return b;
}
----------------------------------------

Here is the result of running g++ -v tmp.c++ tmp1.c++
