Consider the following:

#include <iostream.h>


class Exception{
  public:
    Exception() {}
    ~Exception() {}
};

std::string foo(bool throwException)
{
   if( throwException ) {
     throw Exception();
   } else {
     std:: string x = "hello world";
     return x;
  }
}

int main(int argc, char** argv)
{
  try {
    const std::string & str  = foo(true);
  } catch(...) {
    cout << "Caught an exception" << endl;
  }
  return 0;
}

Compiled it for POWERPC target and upon execution, it segmentation faults and 
dumps a core. From the core, it is trying to delete the std::string object 
pointed at by str (reference to string to be returned from foo) while unwinding 
the stack.

The same results are obtained if any of the STL classes are used. 

Everything works fine on x86 targets. 


It seems that the gcc compiler is breaching  ISO/ISE 14882:2003 12.2/5 upon 
throw of an exception.

Thanks
