Trying to compile a Win64 debug version of druntime with current githead, I get
an ICE when compiling druntime/src/rt/typeinfo/ti_Acfloat.d 

A reduced test case is

module test;

void foo(cfloat x)
{
}

cfloat[] a;

void main()
{
    foo(a[0]);
}

building with "dmd -m64 test.d" yields "Internal error: .\backend\cgcod.c 561" 

This does not happen when I compile with -m32 or if I use cdouble or creal or
if I pass a cfloat that is not read from an array. With optimizations, I get
"Internal error: .\backend\cgcod.c 188".

I don't know if this applies to other OS aswell, maybe issue 6772 is related.

But cfloats are deprecated. Isn't it _much_ better to focus the
development/debugging efforts on features that are not deprecated?
