inout parameters are passed by reference, i.e. they are actually a pointer. The
sample code is using inline assembler, referencing the inout parameter. So, the
inline assembler:

    void foo(inout real r)
    {
        asm
        {   fld r;

is actually loading a *pointer* and treating it as if it were a real.

Inline assembler does exactly what you tell it to do. To make the above work,
use instead:
            mov EAX,r ;
            fld real ptr [EAX] ;

Not a compiler bug.
