This code:

class X {
  int member;  
};

volatile X a;
X b = a;

Fails with the error:

prog.cpp:6:7: error: no matching function for call to ‘X::X(volatile X&)’
prog.cpp:6:7: note: candidates are:
prog.cpp:1:7: note: X::X()
prog.cpp:1:7: note:   candidate expects 0 arguments, 1 provided
prog.cpp:1:7: note: X::X(const X&)
prog.cpp:1:7: note:   no known conversion for argument 1 from ‘volatile X’ to ‘const X&’

Is there any way I can get the compiler to generate a volatile copy constructor for me?
