Thanks, for the prompt response.

I downloaded the latest version from CVS.  Unfortunately, there is still a
problem in the build_op_delete_call function.

The compilation of the following program fails with a segault when
-fvolatile is used but not without.  Note the addition of the constructor
to class bar.

2>@awk[114]% more test3.cc

class bar {
  public :
    bar() { }
    void * operator new ( unsigned int , void * storage ) { return (void *)1;}
};

class foo {
  public:
    void mem ( ) {
        new ( 0 ) bar;
    }
};

2>@awk[115]% g++ test3.cc -c

2>@awk[116]% g++ test3.cc -fvolatile -c
test3.cc: In member function `void foo::mem()':
test3.cc:11: internal error: Segmentation fault
