Confirmed, reduced testcase as far as I can get it (and is willing to try at
this point):
typedef unsigned long uint32_t;
typedef volatile uint32_t* const hwreg_t;
struct RegisterLayout
{
uint32_t intmask;
};
struct Controller_t
{
Controller_t();
inline void
disableInterrupt()
{
*mpMaskRegister = 0;
};
static hwreg_t mpMaskRegister;
};
extern char SimulatedRegisters[];
hwreg_t Controller_t::mpMaskRegister = (reinterpret_castvolatile
RegisterLayout*(SimulatedRegisters))-intmask;
Controller_t::Controller_t()
{
disableInterrupt();
}
