Bug 8966 – ICE(cgcod.c) when passing cfloat argument with indirection

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.

Correct test case: https://github.com/D-Programming-Language/dmd/pull/2370

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