Hi,

  The following short program gets a segmentation fault on the sparc
for g++ 1.27:

----------------------------------------
#include <stream.h>

const int Max_Buf = 1000;

class foo {
private:
   int j;
   int k;
   static int *Head, *Ptr;

public:
   foo(int i) {
      j = k = i;
   }
   int Return(void) {
      return(j * k);
   }
   void * operator new(long Size) {
      if (!Head) {
         Ptr = Head = (int *) new int(Size * Max_Buf);
      }
      cout << Size << "\n";
   }
};

main() {
   foo Bar(1);
   foo *Bard = new foo(2);

   cout << "Bar.Return() = " << Bar.Return() << "\n";
   cout << "Bard.->Return() = " << Bard->Return() << "\n";   
}
----------------------------------------

Here's the diagnostic:
g++ version 1.27.0
 echo use .cc filename extension!
