This took a couple of hours to dustmite & manually reduce from the vdparser-benchmark in druntime: void foo() { cfloat v2; ulong v1; auto z = v2 + v1; } compile with dmd 2.075 with "-m64" yields: Internal error: ddmd\backend\cg87.c 3680 The same happens with substraction, but not with multiplication. This compiles with dmd 2.072 or with -m32.
