 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()':
