           Summary: ICE(mtype.c) floating point converted to an integer
                    type and passed to a function, when certain
                    incompatible overloads exist
           Product: D
           Version: 2.032
          Platform: x86
        OS/Version: Windows

          Severity: normal
          Priority: P2
         Component: DMD

void qwert(int yuiop, int asdfg) {}
void qwert(long yuiop) {}

void hjkl(real zxcvb) {
    qwert(cast(long) zxcvb);
}
----------
Assertion failure: '0' on line 1566 in file 'mtype.c'

abnormal program termination
----------

Same ICE if:
(a) line 1 is instead
    void qwert(short yuiop, short asdfg) {}
(b) in addition to (a), asdfg is cast to an int instead
(c) line 2 is removed (hence ice-on-invalid-code)

Compiles successfully if:
- line 1 is removed
- cast is changed to int, but function sigs kept the same
- line 1 parameters changed to long
- hjkl is instead
    void hjkl(real zxcvb) {
        long nm = cast(long) zxcvb;
        qwert(nm);
    }
- I use DMD 1.047 instead

This is probably the same as the nasty regression bug 3173. I'd submitted the
patch to Walter just before 2.032 was released, but unfortunately it missed the
deadline. We considered delaying the release of 2.032 by another few days
because of it.

This is a regression. My patch for bug 3173 fixes it. It's not the same as bug
3173, since this is an ice-on-valid-code.
