bus error at virtual method call

[Paul van Hagen]

Hello,

I have built an executable on a Solaris 2.8 (Sparc) workstation with gnu g++
2.95.3.
However, at execution it crashes with a SIGBUS error.

I have used the -O3 level optimizer. The same code runs fine on a Linux
environment, same code, same compiler, different hardware.

I have narrowed it down to a call to a private virtual method that is called
from a public base class method, such as in:

class A
{
  public:
    A() { }
    virtual ~A() { }
    void doSomething(int i)
    {
       // some preparation code using i
      doSomething(); // -> bus error at this call !
    }
  private:
    virtual void doSomething() { };
};

class B
{
  // ... ctor/dtor
  private:
    virtual void doSomething()
    {
       // never gets here!
    }
};

When I compile for debugging (-DDEBUG -g) the problem disappears.

Is there a way to circumvent this problem by refactoring, lowering O level
or perhaps use other compilation flags.

Thx
Paul
