I get an internal compiler error when compiling the code below.  The compiler
error goes away if the "-fno-tree-ccp" is added to the command line.  The exact
error message is:

gccbug.cpp: In constructor 'Controller_t::Controller_t()':
gccbug.cpp:41: internal compiler error: in get_indirect_ref_operands, at
tree-ssa-operands.c:1453

This is not a duplicate of #21167.  That patch already appears to be in 4.0.2.

The "-v" option gives this configuration:
Using built-in specs.

The exact code that generates this error is:
------------------
// Compile with -O2.
// compiler error goes away if "-fno-tree-ccp" is added

typedef unsigned long uint32_t;

// compiler error goes away if "const" is removed
typedef volatile uint32_t* const hwreg_t;

struct RegisterLayout
{
    uint32_t intmask;
};

struct Controller_t
{
public:
    Controller_t();

    inline void
    disableInterrupt()
    {
        *mpMaskRegister = 0;
    };

    static hwreg_t mpMaskRegister;
};

extern char SimulatedRegisters[];

// compiler error goes away if "volatile" is remove
#define MACHINE                                                         \
    (reinterpret_cast<volatile RegisterLayout*>(SimulatedRegisters))

hwreg_t Controller_t::mpMaskRegister = &MACHINE->intmask;

Controller_t::Controller_t()
{      
    disableInterrupt();
}
