           Summary: va_arg doesn't work with idouble and ifloat
           Product: D
           Version: unspecified
          Platform: x86_64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2

Created an attachment (id=927)
test case showing the problem

In 64bit va_arg does not give back the correct pointer for the type idouble and
ifloat. I haven't tested more types so far, but I guess cfloat and cdouble will
give problems, too

see attached test case. In 32bit the outputs are the same, in 64bit not.

I only tested this on D1, but I assume it will have the same problems on D2

Created an attachment (id=928)
testcase for ifloat, idouble, cdouble, cfloat

I extended the testcase to cfloat and cdouble.

It works with cdouble. and it gives 

   Internal error: backend/cgcod.c 576

with cfloat, so I couldn't test that part.
