hi.  Me again :-)  I finally got access to the 4.1.3 machine that I was 
promised, and I build gcc, pthreads, libg++, gmake, etc. on it 
successfully.

I was able to run simple "helloworld.cxx" style programs using gcc (no 
iostream classes) g++ (with iostream classes), yet unusual behavior with 
the pg++ classes.

It turns out that whether I build libg++ ENTIRELY from pgcc (aka, I never 
installed libg++ until after I installed pthreads, and with the "CC=pgcc 
-O2" and "CXX=pgcc" options turned on) or if I make a normal libg++ in 
/usr/local/ and put a special version of libg++ somewhere, it still 
core-dumps...

I can get the code to compile if I use the standard libg++ libraries, 
compiled without pgcc, but the code does nothing, or Seg faults :-(

Here is the program:

#include <stdio.h>
#include <pthread.h>
#include <iostream.h>

void main()
{
        printf("Hello World\n");
        cout << "Hi Mom!" << endl;
        cout << "Enter a number:";
        int x = 5;
        cin >> x;
        cout << "Wow!  You chose " << x << '!' << endl;
}

here is the output:

sunny <~/testc++>: a.out
Hello World
Segmentation fault (core dumped)

Any ideas?
