Hello, all: 

I'm compiling C++ code using g++ and linking the generated object files
using gcc. Of course, the C++ code uses none of the standard C++ stuff. 

One problem, the executable crashes when a member function of the
virtual inherited class is called. However, the same code works on other
platforms. Here is the C++ code 

extern "C" { 
#include <stdio.h> 
} 

class Shape { 
 protected: 
  int a; 
 public: 
  Shape() { 
    a = 1; 
  } 
  virtual void test () { 
    printf ("shape test! %d\n", a); 
  } 
}; 

class Circle:  public Shape { 
protected: 
  int b; 
 public: 
  Circle() { 
    b = 10; 
  } 
  void test () { 
    printf ("circle test! %d\n", b); 
  } 
}; 


int main () { 
  Shape *s = new Shape; 
  Circle *c = new Circle; 

  s->test(); 
  c->test(); 
} 

The output for this program is 
	shape test! 1 

and then CORE DUMP! 


gcc on the DEC Alpha is 2.5.5 (also tried it with 2.5.7) and the version
on other platform (namely, DEC 3100 running Mach) is 2.3.2. 


any ideas? thanks...
